Gert Ehrlich (born June 22, 1926 in Vienna ; † August 10, 2012 ) was an American chemist and physicist.

Ehrlich fled Austria to the USA with his sister and parents in 1939 because his father was Jewish. From 1944 he studied at the Columbia University , interrupted by military service from 1945 to 1947. He received in 1948 his bachelor's degree in chemistry at Columbia University and was in 1952 Paul Doty at Harvard University with the theme Studies on synthetic polyampholytes doctorate .

As a post-graduate student , he was with Gordon Sutherland at the University of Michigan , working on infrared spectroscopy of macromolecules. From 1953 he conducted research at General Electric in their research laboratories in Schenectady on absorption from gases on solid surfaces. With the field ion microscope he had just invented , he was able for the first time to track individual atoms during diffusion on metal surfaces and to receive images of them. That became his most cited work.

In 1968 he became a professor at the University of Illinois .

There he dealt further with surface phenomena (surface diffusion) at the atomic level, among other things he discovered the Ehrlich-Schwöbel-Barrier (1966). His group also pursued modeling with computer simulations and, after their discovery, used scanning tunneling microscopes .

In 1979 he received the Medard W. Welch Award and in 1982 the Kendall Award from the American Chemical Society . In 1984/85 he was a Guggenheim Fellow at Harvard and in 1992 with a Humboldt Research Prize at the Fritz Haber Institute in Berlin with Gerhard Ertl and Jochen H. Block . In 1986 he became a member of the National Academy of Sciences .
