This item was about John Evershed (1911-1923) who joined Kodaikanal Observatory in 1907 as the Assistant Director and became the Director in 1911. In 1909, Evershed discovered that there is radial outflow of gases in a sunspot. This effect is now Known as the "Evershed Effect". For this seminal work, he was elected to the Royal Society in 1915 and was awarded the Gold Medal of the Royal Astronomical Society in 1916.
