Nikolai Yegorovich Zhukovsky (1847-1921), Russian engineer. Also known as Joukowsky, he pioneered the study of air and fluid flow, which was crucial to a proper understanding of powered flight. He was born in Orekhovo, several hundred kilometres east of Moscow. He studied at Moscow University, and, from 1872, was a professor at the Imperial Moscow Technical School. In 1904, he founded the world's first aerodynamics institute in Kachino, near Moscow. The Joukowsky transform is named after him, as is a crater on the Moon. Photographed on 1 November 1911.
