Hieronymus Fabricius ab AquapendenteDied 21 May 1619 at age 82 (born 20 May 1537).Italian physician, surgeon, anatomist and embryologist who was an outstanding Renaissance anatomist and helped found modern embryology. He studied under, and then suceeded, Gabriel Fallopius. In 1600 and 1612, he published his studies of chick embryo development, which promoted embryology as a field of research, though his understanding was flawed. For example, he believed it was the chalaza (spiral threads that hold the yolk in position inside the egg) that produced the chick, while the yolk was merely present to provide nutrition for the devloping embryo. In 1603, he published his most significant book, De venarum ostiolis, describing the veinous system. His pupil, William Harvey, extended this knowledge of blood circulation.«[also known as: Geronimo, or Girolamo Fabrizio, or Fabrici. DSB gives birth as c. 1533.] |
