Proctor_1

Proctor, Richard Anthony (1834-88), was born in Chelsea, and studied at King's College, London, and St. John's, Cambridge, where in 1860 he was 23rd Wrangler. He early devoted himself to astronomical studies, and gave popular lectures in England, America, and the colonies, besides writing over fifty books, and conducting Knowledge, which he founded in 1881. To him is due the theory of the solar corona and the accurate determination of the rotation of Mars.
