Wilhelm HisDied 1 May 1904 at age 72 (born 9 Jul 1831). Wilhelm His, born in Basel, Switzerland, was a German anatomist and embryologist who created the science of histogenesis, or the study of the embryonic origins of different types of animal tissue. His discovery, in 1886, that each nerve fibre stems from a single nerve cell was essential to the development of the neuron theory. He invented the microtome - a device to slice very thin serial specimens for microscope slides (1865). With it, he could examine embryos. He was the first to accurate describe the human embryo. |
