Archibald Pitcairne, Scottish physician and academic (b. 1652)
Archibald Pitcairne or Pitcairn (25 December 1652 – 20 October 1713) was a Scottish physician.

He was a physician and poet who first studied law at Edinburgh and Paris graduating with an M.A. from Edinburgh in 1671. He turned his attention to medicine, and commenced to practise in Edinburgh, around 1681. He was appointed professor of physic at Leyden, in 1692, resigning his chair. On returning to Edinburgh, however, around 1693, he was suspected of being at heart an atheist, chiefly on account of his mockery of the puritanical strictness of the Presbyterian church. He was the reputed author of two satirical works, 'The Assembly, or Scotch Reformation : a Comedy,' 1692, and Habel, a Satirical Poem,' 1692. He wrote also a number of Latin verses. He was one of the most celebrated physicians of his time.
