Biography:

James Mease (Aug. 11, 1771-May 14, 1846), physician, scientific thinker and author, was one of Philadelphia's most prominent citizens and an ardent booster of both the United States and Pennsylvania. His interests were wide-ranging, as were his contacts with notable figures in science, agriculture and natural history in the United States and abroad.
Mease was born in Philadelphia into a wealthy and patriotic shipping merchant family; during the Revolutionary War his father, John Mease, served in the Philadelphia Troop of Light Horse. James graduated from the College of the University of Pennsylvania, and received an M.D. degree in 1792 from the same institution. He married Sarah Butler, the daughter of a South Carolina senator, in 1800. During part of the War of 1812 the younger Mease served as a hospital surgeon. Mease was one of the managers of the "Company for the Improvement of the Vine," in connection with which he developed a vineyard; he was a prominent member of The Philadelphia Society for Promoting Agriculture, a member, curator, and councilor of the American Philosophical Society, and one of the founders and first vice-president of the Philadelphia Athenaeum.
Mease belonged to an informal international network of scientifically-inclined thinkers who shared information, books, pamphlets, geological samples, seeds, etc. in an ongoing exchange. He wrote to Count Rumford, to Sir Joseph Banks, sent a pamphlet to Cuvier, had a lively correspondence with the Scottish horticultural writer, John C. Loudon, and sent rocks to Donald Stewart, mineralogist of the Dublin Society. On the subject of the Pennsylvania penal system and general criminal reform he wrote to the President of the United States, cabinet department heads, state governors, and numerous federal and state legislators. He was interested in a wide range of agricultural and horticultural topics, in various technologies, in geology, in the medicinal properties of plants. All together these papers render a portrait of a remarkably intelligent, dedicated and thoughtful individual.
