Philadelphia-born Henry Darwin Rogers (1808-1868) was perhaps the first international (overseas) professor employed at the University of Glasgow.
He directed geological surveys of New Jersey in 1835 and Pennsylvania in 1836, becoming a freelance geologist and moved to Scotland in 1855. He was appointed to the Chair of Natural History from 1857, a position he held until his death in 1866. Rogers was also responsible for the care of the Hunterian Museum. His brother, William Barton Rogers, with whom he had founded two high schools in the US, was founder of the Massachusetts Institute of Technology.
