Consul William Sherard, who afterwards left his library and an endowment to the Oxford Garden, wrote in July 1719 that Vice-chancellor Shippen had compelled Bobart, 'my old master,' who was then in weak health, to resign the office of botanic professor, Dr. E. Sandys receiving the post.
He studied botany from 1686 to 1688 in Paris under Joseph Pitton de Tournefort and was a friend and pupil of Paul Hermann in Leyden from 1688 to 1689 who also studied with Tournefort at this time.
