Frederik Ruysch
The Anatomical Preparations of Frederik Ruysch
The botanist and anatomist Ruysch was interested in some of the same things that intrigued Leeuwenhoek such as how fluids move through living bodies. Where Leeuwenhoek used a magnifying glass, Ruysch used injections of tinted wax, among other things, that both preserved the bodies and provided human parts for his dioramas. Ruysch was elected Fellow of the Royal Society in 1715 and visited Leeuwenhoek around that time, as noted in Leeuwenhoek's letters.
One of Ruysch's students was Govert Bidloo.
The Anatomy Lesson of Dr. Ruysch (right; click for larger size) was painted by Jan van Neck in 1683.
Beginning in 1701, Ruysch published ten volumes of descriptions (but few illustrations) of the objects in his anatomy cabinets.
