[The Vesalius of human embryology]

Human embryology was founded 100 years ago by WILHELM HIS, who may rightly be called the "Vesalius of human embryology". 3 landmarks were published in Germany within a quarter of a century: The Anatomie menschlicher Embryonen of HIS, KEIBEL'S Normentafeln, and KEIBEL and MALL'S Handbuch der Entwicklungsgeschichte des Menschen. The staging of the human embryo, now associated with the names of STREETER and O'RAHILLY, was first proposed by MALL in Anatomischer Anzeiger.
