Henri Coand%C4%83

Henri Marie Coand June 1886 November 1972 was a Romanian inventor, aerodynamics pioneer and builder of an experimental aircraft, the Coand1910 described by Coand in the mid1950s as the worlds first jet, a controversial claim disputed by some and supported by others. He invented a great number of devices, designed a flying saucer and discovered the Coand effect of fluid dynamics.

Born in Bucharest, Coand was the second child of a large family. His father was General Constantin Coand, a mathematics professor at the National School of Bridges and Roads. His mother, Aida Danet, was the daughter of French physician Gustave Danet, and was born in Brittany. He was later to recall that even as a child he was fascinated by the miracle of wind.
