1681 - Cornelis de Man

Cornelis de Man (1621-1706) painted this group portrait commissioned by the Delft surgeon's guild in 1681, when Leeuwenhoek was 49. It shows Dr. Cornelis Isaaks 's-Gravesande in the Theatrum Anatomicum on the Verwersdijk poking a cadaver while other members of the surgeons' guild look on, including Dr. Henry d'Acquet in the lower right corner. Leeuwenhoek is standing to 's Gravesande's left with his hand over his heart.
