Adolf Eugen Fick (born 3 September, 1829, in Kassel, Germany; died 21 August, 1901, in Blankenberghe, Flandern) was a German physiologist usually credited with the invention of contact lenses . In 1855 he introduced Fick's law of diffusion , which governs the diffusion of a gas across a fluid membrane. In 1870 he was the first to devise a technique for measuring cardiac output, called the Fick Principle .
