Johann Gaspar Spurzheim (1776-1832) was a German physician who became one of the chief proponents of phrenology, a branch of the neurosciences created approximately in 1800 by Franz Joseph Gall (1758-1828).
Biography
Spurzheim was born near Trier, Germany on December 31, 1776, and studied medicine at the University of Vienna. He became acquainted with Gall in 1800 and was soon hired by him as an assistant. Gall intended to have Spurzheim as his successor and added his name as a co-author to books and publications. In 1812, however, Gall and Spurzheim had a falling out, and Spurzheim started a separate career, lecturing and writing extensively on what he termed 'Drs. Gall and Spurzheim's physiognomical System'. He greatly popularised phrenology, and travelled extensively throughout Europe, achieving considerable success in England and France.
Spurzheim made many alterations to Gall's phrenological system, including an increase in the number of "organs", as well as its organization into a hierarchical system. Spurzheim also used images and busts to illustrate the craniographic approach of phrenology.
