Jens Otto Harry Jespersen (Danish: [ˈʌtˢo ˈjespɐsn̩]; 16 July 1860 – 30 April 1943) was a Danish linguist who worked in foreign-language pedagogy, historical phonetics, and other areas, but is best known for his description of the grammar of the English language. Steven Mithen describes him as "one of the greatest language scholars of the nineteenth and twentieth centuries."

Early life
Otto Jespersen was born in Randers in Jutland, to Jens Bloch Jespersen (1813–1870) and Sophie Caroline Bentzien (1833–1874). He was one of nine children. After his father died the family moved to Hillerød, where his Jutland accent was ridiculed.
As a boy, Jespersen was inspired by works of the Danish philologist Rasmus Rask and the biography of Rask by Niels Matthias Petersen; and with the help of Rask's grammars taught himself some Icelandic, Italian, and Spanish.
Academic life and work
Jespersen's father, grandfather and great-grandfather had been lawyers, and the same was expected of him. He entered the University of Copenhagen in 1877 when he was 17, initially studying law but not abandoning his language studies. In his first year at university, he attended a lecture course by Sophus Heegaard on the history of Evolutionism since the Greeks; this introduced him to the ideas of Herbert Spencer, and later in life he looked back on the course warmly. Teaching languages in a lower secondary school and working from 1880 to 1887 as a stenographer for the Rigsdag (Danish parliament) brought an income that in 1881 allowed Jespersen to shift his focus completely to languages. Following the introduction of a new degree, Skoleembedseksamen, he switched to this, choosing French as the major subject and English as the second minor subject, the first compulsorily being Latin (a language that he hated from then on). He was one of a large number of students who appealed for Latin to be made voluntary, but the appeal was unsuccessful. Thanks to his need for an income, obtaining a Master's degree (in French) took Jespersen a decade, but the delays may well have determined his "habits of wide and self-motivated study".
Jespersen studied under the linguists Karl Verner, Hermann Möller and particularly Vilhelm Thomsen; and beyond linguistics, under Harald Høffding. It was thanks to Høffding that Jespersen was further exposed to the writings and ideas of Darwin, Mill and Spencer, and to introspective psychology.
In 1887 Jespersen passed Skoleembedseksamen. For French, he chose to be examined on Diderot, from a lasting enthusiasm for the ideals of the French Revolution and the Enlightenment. Throughout his life Jespersen remained faithful to the ideals and methods of his early teachers. Positivist and evolutionary attitudes, physiological and psychological methods in their classical form, and finally, liberal humanism were essential to his character.
Jespersen's views on language owed less to theoretical considerations than to a practical and thus largely functional conception of language; as a language theorist, Jespersen could remain tethered to reality thanks to the common sense fundamental to his character. Even when making such bold proposals as that of the "progress" of a language, he could avoid extremes.
In 1887, soon after passing the Skoleembedseksamen, Jespersen went to London, where he met the phoneticians Wilhelm Viëtor, Alexander Ellis and Henry Sweet. In October he went on to Oxford, where James Murray told him of progress towards A New English Dictionary, and where he heard lectures by the Assyriologist Archibald Sayce and others.
Language teaching
At the end of the 19th century the teaching in Denmark of contemporaneous foreign languages was ossified, and very similar to that of long-dead classical languages. This was despite the belief of N. M. Petersen, expressed decades earlier, that pupils should be encouraged to acquire a second language in the way that they had acquired their first, and indeed despite the writings of Jan Amos Comenius in the 17th century.
In 1886, Jespersen, August Western and Johan August Lundell cofounded a Scandinavian group for a revitalization of language teaching, naming the group "Quousque Tandem" after Wilhelm Viëtor's pseudonym as author of the 1882 pamphlet Der Sprachunterricht muss umkehren!. The group opposed the use of theoretical grammar and translation exercises, advocating in its place the teaching of a language in its spoken and living form by the "direct" method, informed by phonetics:
The pupils should begin by recognizing words and short sentences by ear, and repeating them, and only then should they learn to read them. A correct pronunciation should be secured with the help of phonetic transcription.
As a campaigner, Jespersen was an extremist: Hjelmslev writes that this was an area where his normal moderation and common sense were counterbalanced by a revolutionary fervour, and that he was a "Jacobin" among linguists.
Jespersen's first book (1884) was a Danish translation, Praktisk Tilegnelse af Fremmede Sprog ("Practical acquisition of foreign languages"), of Die praktische Spracherlernung, by Felix Franke. Both Franke (also born in 1860) and Jespersen first assumed that the other was much older than himself, but from its start in 1884 their correspondence quickly became a lively discussion (about two hundred letters and postcards survive) of such matters as second language education and phonetic scripts; it was cut short in 1886 when Franke succumbed to tuberculosis.
In an article published in 1886 (and elaborated in his 1901 book Sprogundervisning, translated as How to Teach a Foreign Language, 1904), Jespersen argued for the following principles in language teaching:
Teaching should be based on spoken rather than written language. To this end, at early stages of language teaching, only a phonetic script should be used, and this script should be clear and precise.
Phonetics
Jespersen's interest in phonetics was prompted by Henry Sweet's Handbook of Phonetics (1877), and the lectures of Vilhelm Thomsen. In the 1880s, inspired by Melville Bell and other British phoneticians, Jespersen developed what he first called an "analphabetic" system – which, in order "to avoid ridicule", he later termed an "antalphabetic" system – that used a series of three variables for any phone: lowercase Roman for the passive articulator, lowercase Greek for the active articulator, and numerals and more for "the degree and shape of the aperture at a place of constriction". Jørgen Rischel points out that a given "anatomical feature" can be labelled according to its use: thus rather than simply "uvular", the role of the uvula can be described as "a passive articulator in uvular consonants but an active articulator in nasalized sounds".
In June 1886, he became a member of the Phonetic Teachers' Association, later renamed the International Phonetic Association (IPA). The idea of creating a phonetic alphabet that could be used by every language was first put forward by Jespersen in a letter he sent to Paul Passy. Jespersen's transcription system for English, used in John Brynildsen's A Dictionary of the English and Dano-Norwegian Languages (1902–1907), is very close to that of Daniel Jones, which it preceded by some years. Language-specific systems were not unusual at the time (Johan A. Lundell published a Swedish dialect alphabet in 1879, Johan Storm devised Norvegia for Norwegian in 1884); and Jespersen devised a system, Dania, for the phonetic transcription of Danish (1890), which has remained in use for philological, dialectological and lexicographic work in Danish. Jespersen was sceptical of a single phonetic transcription system for universal application, and did not use the IPA's International Phonetic Alphabet.
With continued encouragement by Thomsen and a new friendship with Paul Passy, whom he met in Paris, Jespersen was well informed on phonetics. His own major work on this was Fonetik, published in 1897–1899. In it, Jespersen bases his descriptions on his observations of his own production of sounds in a variety of languages, where this production satisfies native speakers. Jespersen was keen to supplant metaphorical and impressionistic terms with those that described the vocal tract, and had considerable success. Jørgen Rischel calls Fonetik "a landmark in Danish phonetics because of its terminology", much of which has lasted.
The Danish-specific material within Fonetik was republished in 1906 within the booklet Modersmålets Fonetik ("Phonetics of the mother tongue"). This treated not only the sounds of Danish but also its prosody, an area in which Jespersen was a pioneer. Repeatedly reprinted, the booklet was long used as a standard textbook.
Concentration on English
While still regarding himself as less of a scholar of English than a scholar of French, Jespersen published Kortfattet engelsk Grammatik for Tale- og Skriftsproget ("A concise English grammar for the spoken and written language") in 1885. Most unusually for a grammar book, this employed phonetic script. Inge Kabell comments: "All other grammars of English published in Denmark were for many, many years to come modelled on it and all middle-aged Danes have been taught English according to the principles found in it."
Henry Sweet's views on phonetics, grammar, and historical linguistics, and his concentration on English, had a great influence on Jespersen, whose choice of the case system of English as the subject of his doctoral dissertation was probably also prompted by advice from Vilhelm Thomsen to prepare for a chair in English at the University of Copenhagen that would soon be vacant upon the retirement of George Stephens. He successfully defended his dissertation in 1891. Once installed as chair, Jespersen devoted most of his energy to the study and teaching of English, but he retained his broader interests. His prolific output was of great importance for the linguistic study of all aspects of English, for linguistics in general, and to a lesser degree for Nordic philology. Jespersen was the first great linguist to hold the chair of English at the Copenhagen, while his friend Kristoffer Nyrop had much the same role for the university's chair of French.
Jespersen continued as chair of English until he retired in 1925, following his resolve not to continue after reaching 65, in order to help make way for younger scholars.
General syntax
Jespersen advanced the concepts of rank in two papers: "Sprogets logik" (1913) and "De to hovedarter af grammatiske forbindelser" (1921); and in the latter, nexus as well. In this theory of ranks, Jespersen removes the parts of speech from the syntax, and differentiates among what he names primaries, secondaries, and tertiaries; for example, in well honed phrase, the primary is phrase, this being defined by a secondary, honed, which itself is defined by a tertiary, well.
The term nexus is applied to sentences, structures similar to sentences, and sentences in formation (in which two concepts are expressed in one unit; e.g., it rained, he ran indoors). This term is qualified by a further concept called a junction which represents one idea, expressed by means of two or more elements, whereas a nexus combines two ideas. Junction and nexus have had a mixed reception. Hjelmslev finds the distinction between them confused, and Jespersen's theory of them in need of revision: a contrast to his refinement in "Tid og tempus" (1914) of Sweet's distinction between tense (Danish tempus) and time (Danish tid).
Jespersen's work helped point the way towards linguists' current understanding of a grammatical head.
In Hjelmslev's opinion, Negation in English and Other Languages (1917) offers a great number of observations and considerable food for thought, but fails to constitute a general examination of negation, for which purpose it would have to be based on more solid materials, from a greater variety of languages (the overwhelming majority of the examples examined are from the Indo-European languages of west Europe). Jespersen coined the terms paratactic negation and resumptive negation (negation with an element added to the end of the sentence to strengthen the already negative meaning of the sentence); he also advanced understanding of negative concord.
In The Philosophy of Grammar (1924) Jespersen challenges the accepted views of common concepts in grammar and proposes corrections to the basic definitions of case, pronoun, object, voice etc., and further develops his notions of Rank and Nexus. In the 21st century this book is still used as one of the basic texts in modern structural linguistics.
With The Philosophy of Grammar particularly in mind, Noam Chomsky remarked in 1975: "I think it is fair to say that the work of recent years tends generally to support the basic ideas that Jespersen outlined 50 years ago, and extends and advances the program that he outlined."
Evolution and progress of languages
From the time of his doctoral thesis of 1891 (primarily about the disappearance over time of the case system of Old English), Jespersen maintained that language did not merely evolve over time but progressed, a notion originally inspired by Spencer's ideas on the progress of language. For the publication of the thesis in English translation (1894), Jespersen moved its subtitle to its main title, for Progress in Language: With Special Reference to English. Within it, he wrote "That language ranks highest which goes farthest in the art of accomplishing much with little means, or, in other words, which is able to express the greatest amount of meaning with the simplest mechanism." Jespersen considered the efficiency of a language's phonology, lexicon and grammar, his view of efficiency in grammar being a reaction to contrasting estimates of "synthetic" and "analytic" inflectional languages held by the brothers August Wilhelm Schlegel and Friedrich Schlegel, and Wilhelm von Humboldt.
August Schleicher was a conspicuous proponent of the idea that older languages such as Latin had attained a synthetic optimum, and languages that derived from these tended to degrade via the analytic towards an "isolating" extreme, the degree of degradation of a language increasing with "the richness and eventfulness of its speakers' history". Jespersen proposed the reverse, criticizing the needless complexities of synthetic grammar, ascribing Schleicher's evaluations to "a grammar-school admiration, a Renaissance love of [Latin and Ancient Greek] and their literatures", and commenting that "The so-called full and rich forms of the ancient languages are not a beauty but a deformity".
Whereas Schleicher conceived language as a biological phenomenon, and thus subject to processes such as maturation, ageing and death, linguists of the mid 19th century such as Georg Curtius, Johan Nikolai Madvig and William Dwight Whitney emphasized language as a human-developed tool for communication. By the end of the century this became the received conception of language.
Jespersen thought of the uses of language as needing a balance between two factors: the ease of the speaker's expression of ideas, and the distinctness of that expression (and thus the ease of comprehension for the listener). The proximate sources of the pair were Georg von der Gabelentz's Bequemlichkeitstrieb ('drive to comfort') and Deutlichkeitstrieb ('drive to distinctness', although by Deutlichkeit Gabelentz meant something broader than Jespersen's early formulations of distinctness). Although Jespersen later recognized that distinctness should include playfulness, vividness and other factors, the ability to communicate remained foremost.
Child language
The work of Jespersen's that addresses child language most extensively is Nutidssprog hos Børn og Voxne ("Today's language in children and adults", 1916), and its second edition, Børnesprog: En Bog for Foraldre ("Children's language: A book for parents", 1923). Their content, and that of Sproget: Barnet, Kvinden, Slægten (1941), is summarized within Language: Its Nature, Development, and Origin (1922). Jespersen distinguishes himself, as a linguist, from psychologists and educationalists such as Wilhelm Wundt, William Stern, and Vilhelm Rasmussen, criticizing them for faults such as the ambiguity of estimates of vocabulary when what are counted are ill-defined, and criticizing Wundt in particular for his belief that children participate only passively in what is largely an environmental generation of language.
Jespersen writes of three major stages in first language acquisition: screaming (perceived as language-like by the addressee, if not by the producer), babbling, and talking; and of talking as itself having two stages: own language and common language. He observes that production of speech comes later than understanding (although it can be hard to gauge understanding when not accompanied by production). He deals with issues of lexical semantics, and "a child's acquisition of his mother tongue is, in general, a complex process of guessing, supposing and inventing, not only in the field of language but also in the fields of reality and conception". Children's inventiveness encompasses conversion and blending. Taking the use of prepositions to illustrate the acquisition of syntactic structure, Jespersen points out that what linguists now regard as preposition phrases first appear as formulas (thus to might first appear in "go to bed") and only later in novel combinations.
Jespersen emphasizes the role of young children's linguistic awareness: although they lack the ability to talk about language, awareness can be observed from their reactions to errors by others, from their hesitations, and from their playful alterations of language.
Jespersen also considers the relationship between meanings of words in child language and the concepts held by those children; he suggests that the influence can work in either direction.
International auxiliary languages
Jespersen applied both his theories on grammar and his ideas of efficiency of expression into the quest for an international auxiliary language.
It is true that towards the end of his life Jespersen expressed some qualms about the time and energy he had invested in [artificial languages; but his] interest in the matter covered practically his whole life, from his rejection of Volapük in his student days to suggested reforms in his own creation Novial a few years before his death.
In 1907 Louis Couturat called a meeting of the Delegation for the Adoption of an International Auxiliary Language to decide on a single language for recommendation for international use. As an Anglicist, Jespersen might have been expected to back English for this role, but he rejected such a notion on the grounds that:
a deliberate choice of any one [national] language for such a purpose would meet with unsurmountable difficulties on account of international jealousies
each of them is several times more difficult than a constructed language need be
As for constructed languages, these were thought of as having either of two goals. There were languages primarily designed to encourage clarity of thought, and those primarily based on (but simplifying) existing, widely spoken languages—although examples of the former type had a tendency to develop towards the latter type. Volapük, which had approached the former (and whose words were built on unrecognizable roots), had recently suffered a rapid decrease in speaker population, eclipsed by Esperanto. Thus the favourites for endorsement by the Delegation were Esperanto (which had regular morphology and was largely based on Romance languages), and Idiom Neutral (which had less stress on regularity and was based on what was already shared by the most prominent languages of Europe). Of the two, Idiom Neutral was more to Jespersen's liking.
A complex and shady process involved the sudden nomination by somebody using the pseudonym "Ido" of a newly conceived revision of Esperanto. Despite learning of the deception made by or for the pseudonymous reviser, and despite his anger over this deception, Jespersen believed candidate languages should be judged purely on their merits, and that this revision (which itself came to be called Ido) was a significant improvement over Esperanto in its state at the time. However, L. L. Zamenhof, Esperanto's creator, was opposed to it, as was the Esperantists' Lingva Komitato, and Ido became a rival of Esperanto. Jespersen collaborated with Louis Couturat and others on International Language and Science (1910), a book advocating its adoption; and became president of an Ido academy. But although a significant increase in its number of speakers would have required Ido to mobilize its speakers and evangelize, such a project did not attract Jespersen, who wanted "a language for the brain, not for the heart".
English
Terms related to English that were introduced by Jespersen and are still widely used today include cleft sentence, content clause, light verb, mass noun, quantifier, and yes-or-no question. Jespersen's writings have also influenced today's conceptions of existential sentence.
In his own work The Syntactic Phenomena of English (1988), James D. McCawley attributes various of his analyses, or the insights pointing towards them, to Jespersen: raising; "worthwhile criticism of traditional systems of parts of speech" and classification of what are traditionally termed "subordinating conjunctions" (as in "You must look at this before you leave") as prepositions with sentential objects; and more specifically, classification of that in relative clauses (as in "The necktie that he bought was polyester") not as a relative pronoun but as a complementizer. Asked how the 20th-century Dutch grammarians of English Hendrik Poutsma, Etsko Kruisinga and R. W. Zandvoort compared with Jespersen, McCawley replied: "Of course, Jespersen is in a class by himself. He was a fantastically original, broad, and deep thinker."
Robert I. Binnick calls Jespersen "one of the greatest students of the English language . . . , at once the last of the traditional grammarians and the first modern linguist–grammarian".
Jespersen's specialism for the longest period was the English language. His most celebrated work, and easily his most expansive, was A Modern English Grammar on Historical Principles, published in six "parts" (volumes) during his lifetime, from 1909 to 1942, and a seventh, posthumous part in 1949. The first part is devoted to phonetics (much of it historical), the sixth to morphology (both derivational and inflectional). The other five are devoted to syntax, which Jespersen particularly enjoyed.
Writing in Jespersen's obituary, Helmslev calls A Modern English Grammar a "monumental work", one that "will maintain its immense value for an incalculable future thanks to the rich documentation of facts it provides".
Growth and Structure of the English Language (1905, and reprinted at numerous times thereafter) is a broad history of the English language. It won Jespersen the Prix Volney. In 1989, Hans Frede Nielsen wrote that:
Women's language
Jespersen has been cited as "a pioneer in the study of women's language [and] often quoted for his views on what he believed to be the biologically determined nature of women's usage" – although "[a] product of his own day and age".
Linguists since Jespersen have been less patient with the content of "The woman", chapter 13 within his book Language: Its Nature, Development and Origin (1922): "he manages to include every stereotype about women that was current at the time"; "[the chapter offers] a compendium – and a grim one for that matter, filled with prejudices and misogyny – of long-standing commonplaces on women's contribution to the development of language."
Margaret Thomas writes:
Jespersen's Chapter 13 is now read as the prime early example of conventional stereotypes and preconceptions about women's language that consider it inherently defective relative to men's language. As such, Jespersen's text is introduced into accounts of the history of language and gender studies in tones that range from detached amusement to derision.
Thomas continues by summarizing how Deborah Cameron reprints what she calls "Jespersen's notorious chapter" in toto, Kira Hall describes it as "infamous", Patrick Mahony demonstrates how it exhibits "androcentric ideology" and "chauvinism", and Jennifer Coates makes multiple references to Language, Its Nature, Development and Origin as a whole.
Chapter 13, "The woman", is one of five chapters making up "Book III" of Language: Its Nature, Development and Origin, a Book in which "Jespersen describes and speculates about the influence of what he considers three other major factors in language change": multilingualism and language contact, pidgins and creoles, and women. While claiming that the differences between women's and men's language contribute to such change, his descriptions of these differences tend to make limited concessions to claims made by others, downplaying their scope or significance Thomas summarizes Jespersen's judgments as made in a tone "not so much distasteful, much less scornful, toward women and women's language as it is indulgent and condescending"; "Jespersen's assessment of women's language overall cannot be represented as disparaging"; he "does not seem to present women's language as a deformed version of men's language".
Scholarly influences and allegiances
Niels Haislund comments:
The three Danish scholars Vilhelm Thomsen, Karl Verner and Hermann Möller, Johan Storm the Norwegian (Englische Philologie), and Sweet probably are those teachers to whom Otto Jespersen owes most, no doubt he was Sweet's dearest pupil.
During the decades of his activity, Jespersen followed what other, younger linguists were doing but refrained from unreservedly welcoming any advance, let alone from aligning himself with any new approach. He remained individualistic, but "there was a conservative streak in his radicalism" as he seemed to take seriously only the standpoints that had influenced him in his youth and to interpret newer work as mere repetition of this or that older theory.
Hans Basbøll sees many followers of Jespersen in Denmark. He has coined the term "New Jespersen School" (Ny-Jespersenianerne) for "the main editors of [Den store danske Udtaleordbog (a major pronunciation dictionary for Danish)], namely, Lars Brink, Jørn Lund and Steffen Heger, and their collaborators and pupils"; their major achievement aside from SDU has been Brink and Lund's two-volume historical phonetics work Dansk Rigsmål (1975).
Rather than naming Jespersen's adherents in each of the various other areas of linguistics of interest to Jespersen, Basbøll chooses to describe only a single line of succession, in the study of Danish grammar. In the preface to his 1901 book Synspunkter for Dansk Sproglære, H. G. Wiwel expresses his gratitude to Jespersen, who in turn praised Wiwel's book, if guardedly. The book harshly criticized the work of Kristian Mikkelsen: unjustly so, in the opinion of Paul Diderichsen. According to Basbøll, in a "large scientific grammar of Danish" of 2011 by Erik Hansen and Lars Heltoft, Wiwel is among the earlier grammarians who "play a significant role", and so Jespersen "still has a heavy share of today's tradition of Danish grammar".
More broadly, Olli O. Silvennoinen sees Jespersen's compatibility with, or encouragement for, late 20th-century functionalism, and "communicative pressures on language structure" (thanks to his "Darwinist and teleological approach to language change"); mainstream generative grammar (thanks to his "emphasis on universal principles underlying superficial variation across languages"); non-mainstream generative grammar (thanks to his "empirical richness and theoretical depth"); and corpus linguistics (thanks to copious provision of attested examples).
Travels and honours
Jespersen visited the United States twice: he lectured at the Congress of Arts and Sciences in St. Louis in 1904, and in 1909–1910 at the University of California at Berkeley, Columbia University (New York), the University of Chicago, Harvard University, and Wellesley College (Wellesley, Massachusetts).
After his retirement in 1925, Jespersen remained active in the international linguistic community. As well as continuing to write, he convened and chaired the first International Meeting on Linguistic Research in Geneva in 1930, co-chaired the first International Congress of Linguists in The Hague in 1928, and presided over the fourth in Copenhagen in 1936.
Jespersen received honorary degrees from Columbia University (1910), the University of St Andrews in Scotland (1925), and the Sorbonne in Paris (1927). He was one of the first six international scholars to be elected as honorary members of the Linguistic Society of America. He was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1931.
Books by Jespersen
Even Hovdhaugen et al. describe Jespersen's output:
[Jespersen's] textbooks and numerous other books gave readers balanced, although not uncritical, information on what was going on in the field of linguistics. Jespersen had a broad theoretical orientation, was interested in all subsystems of language, and invoked examples from many different languages in a way that made him a precursor of language typology.

Political and other views
Jespersen was "an idealist and a pacifist"; and "It is no surprise that Jespersen, with his communicative view of language, his work in foreign language teaching, and his pacifism, should have been attracted to the idea of an international language."
He was "a rationalist and a radical". And "typical of his approach" was Jespersen's application of:
the formula I put forward in 1908, and which since then has been very often quoted by Idists: That international language is best which in every point offers the greatest facility to the greatest number (modelled, of course, on Hutcheson's and Bentham's famous dictum: That action is best, which accomplishes the greatest happiness for the greatest numbers).
Politically, Jespersen leant to the left:
By temperament he belonged to no party for he could never endorse any party-political platform to the full, but he was closest to the Social Democrats in their ideas about social justice, equal opportunity and the like
He had a "dislike of anything that is stilted and pretentious and aimed at making the writer appear more important than he is".
Lack of respect for authority and tradition was an important part of Jespersen's personality. . . . Intellectually Jespersen's inclination to go his own way expressed itself in scepticism and an urge to contradict.
Personal life
As a student, Jespersen enjoyed chess and reading French and English literature.
Jespersen married Ane Marie Djørup on 13 April 1897; the couple, later together with their son (Frans), lived in Frederiksberg (administratively outside Copenhagen but geographically part of it), until their move in 1901 to Ermelundsly, a large house in Jægersborg, near Gentofte. In 1934 they again moved, to Lundehave, a large house in the outskirts of Helsingør, provided by the Royal Danish Academy of Sciences and Letters for a distinguished academician.
Ane Marie died on 30 March 1937. Jespersen became ill in December 1942; he died on 30 April 1943, and his urn was interred in a cemetery at Helsingør.
