Adolf Eugen Fick was a German-born physician and physiologist.
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.
Fick managed to double-publish his law of diffusion, as it applied equally to physiology and physics. His work led to the development of the direct Fick method for measuring cardiac output.
