Wilhelm His: Microtome inventor

Wilhelm His (1831-1904), great Swiss anatomist and embryologist, professor of the Department of Anatomy in the University of Basel and Leipzig. His, made ​​the first attempt to fully study the different stages of the human embryo. To this end, he introduced important technological advances that allowed a more comprehensive understanding of the embryo, marking a milestone in the development of Embryology as a Science. One of his main contributions was the invention of the microtome in 1866, allowing the embryo to be reconstructed from histological sections. Another of his greatest inventions was the embryograph, instrument that allowed the visualization of embryos at low magnification and reconstruct on paper the histological sections. Much of his research on human embryo development is reflected in the work entitled Anatomie der menschlichen Embryonen (1880-1885). The invention of the microtome and the embryograph, the reconstruction from histological sections, and the improved fixation techniques, allowed the detailed study of the internal and external morphology of the human embryo, which until then was a virtually unknown being. Because of his great contributions in the field of Embryology he is granted the name of “Vesalius of human Embryology.”
