Already at 1000 posts in the afternoon, so let's hit #3. Figure we could also use a thread to watch Furbush try to beat the rancid fiends from Orange County and so it can be two things.
The son of Dr. John Nicholson, a biblical scholar, was born at Penrith, Cumbria on 11 September 1844. He was educated at Appleby Grammar School and at the universities of Göttingen (Ph.D., 1866) and Edinburgh (D.Sc., 1867; M.D., 1869). Geology had early attracted his attention, and his first publication was a thesis for his D.Sc. degree titled On the Geology of Cumberland and Westmoreland (1868).
In 1871 he was appointed professor of natural history in the University of Toronto; in 1874 professor of biology in the Durham College of Science and in 1875 professor of natural history in the University of St. Andrews. This last post he held until 1882, when he became Regius Professor of natural history in the University of Aberdeen.
