Early life and education
Fick began his work in the formal study of mathematics and physics before realising an aptitude for medicine. He then earned his doctorate in medicine from the University of Marburg in 1851. As a fresh medical graduate, he began his work as a prosector. He died in Flanders at age 71.
In 1855, he introduced Fick's laws of diffusion, which govern the diffusion of a gas across a fluid membrane. In 1870, he was the first to measure cardiac output, using what is now called the Fick principle.
