History
John Evershed (1864-1956) was an English astronomer who, in 1909, discovered the horizontal motion of gases outward from the centres of sunspots, a phenomenon sometimes called the Evershed effect. In 1906, Evershed became assistant director of the Kodaikanal and Madras observatories in India, later becoming director. Evershed retired in 1923, returning to England; in 1925, he built his own solar observatory at Ewhurst.
