Hans Ussing

Hans Henrikson Ussing ( born December 30, 1911 in Soro Akademi; † 22 December 2000, Herlev Hospital, Copenhagen) was a Danish zoologist. He is best known for the invention of the Ussing chamber. In the early 1950s he described as the first ion transport through the skin of amphibians.

His father Henrik Ussing, a leading folklorist, was a lecturer and historian at the Soro Akademi, his mother, born Jutta Hansen was also a teacher. In 1929 he graduated from the Academy graduated from high school with honors.

He studied at the University of Copenhagen, biology and geography. He also attended lectures at JN Brønsted in physical chemistry. In 1934 he received his Master degree with honors.

At the beginning of his career Ussing examined on the expedition of Lauge Koch zooplankton in East Greenland. On the basis of this material was built in 1938 his doctoral thesis. Since 1935 he worked at the Institute of his PhD August Krogh.

At the same time studied August Krogh, George de Hevesy and Niels Bohr opportunities artificial radioisotopes to explore the metabolic transport in living organisms. Ussing was able to demonstrate the active transport of sodium ions across the cell membrane against the osmotic pressure. This move further progress in the investigation of the intestine, kidney and breathing by biologists and physicians.

In 1940 he married Anne Marie Fox, with whom he had two children.
