Frederik Ruysch
Frederik Ruysch (; March 28, 1638 – February 22, 1731) was a Dutch
botanist and
anatomist. He is known for developing techniques for preserving anatomical specimens, which he used to create dioramas or scenes incorporating human parts. His anatomical preparations included over 2,000 anatomical, pathological, zoological, and botanical specimens, which were preserved by either drying or
embalming. Ruysch is also known for his proof of
valves in the
lymphatic system, the
vomeronasal organ in snakes, and ''arteria centralis oculi'' (the central
artery of the eye). He was the first to describe the disease that is today known as
Hirschsprung's disease, as well as several pathological conditions, including intracranial
teratoma,
enchondromatosis, and
Majewski syndrome.
