Johann Friedrich Julius Schmidt

Johann Friedrich Julius Schmidt was a German astronomer and geophysicist. He was the director of the National Observatory of Athens in Greece from 1858 to 1884. Julius Schmidt was tireless in his work, it was suggested by William Henry Pickering that he perhaps devoted more of his life than any other man to the study of the Moon. During his lifetime, he made some of the most complete lunar maps of the 19th century.
