Adam Steuart was a Scot, but nothing is known of his upbringing. He died at Leiden in 1654 and on his own testimony had spent most of his career on the Continent. Both in his own writing and in the correspondence of Robert Baillie he is accorded the title ‘Doctor’. That Baillie considered him a potential college principal in Scotland means that Steuart was a qualified minister, but in print he denied holding any Church appointment. His first significant post was as Professor of Philosophy at the French Protestant College of Saumur, where he appears to have succeeded Franco Burgersdijk in 1619. The College ran out of funds and Steuart returned briefly to Scotland. He settled as Professor of Philosophy at Sedan in 1622, marrying a French lady, Marie Lemercier, in the same year.
