William MaclureDied 23 Mar 1840 at age 76 (born 27 Oct 1763). Scottish-American, born to wealth in Ayr, Scotland, William Maclure moved to the U.S. in 1778. He was an educational reformer and a geologist who is known for his geological map - the first true geological map of any part of North America and one of the earliest such maps compiled. Before 1800, he had owned businesses in the new country, traveled extensively in Europe, and joined the American Philosophical Society. Through a number of years, Maclure traveled and resided in France, Italy, Paris, Switzerland, and Spain. When Benjamin Silliman organized the American Geological Society in 1819, Maclure was elected president.
