Early life and education
Born in 1696, Stephens was educated in Dublin before studying natural philosophy at the University of Glasgow in 1715. He then moved to Leiden University, a leading center for medical and botanical studies, where he earned his medical doctorate on 15 July 1718. Upon returning to Dublin, he received both Bachelor and Doctor of Medicine degrees from TCD in 1724.
Career and achievements
Stephens was appointed lecturer in botany at TCD, likely in 1724 or 1725, succeeding Henry Nicholson. His most notable contributions include:
Catalog of the Physic Garden (1726): A detailed record of over 500 plant species, presented to the Botanical Society of London on 22 October 1726.
Botanical Elements (1727): Published lecture notes intended to aid students, as Stephens noted it was "impossible to expect that they should acquire a distinct and permanent knowledge of botany by a bare attendance upon one lecture."
Stephens was elected a Fellow of Trinity College Dublin in 1728, having already become a Fellow of the Royal Society in 1718.
Later life and legacy
In 1733, Stephens succeeded William Smyth as lecturer in chemistry, ending his formal role in botany. He continued his academic work until his death in 1761. His contributions helped sustain Trinity’s early botanical studies, bridging the gap between Nicholson’s foundational work and later developments in the field.
