Administrative/Biographical history:

Benjamin Thompson was born in Massachusetts in 1753. He became interested in science when young. In 1772 he married Sarah Rolfe, a well-connected heiress, and became a landowner and a major in the New Hampshire militia. He fought for the British during the American Revolution and moved to London in 1776, where he continued to serve in the British army, spending much of his time in Bavaria and taking part in the French Revolutionary Wars. He carried out scientific work throughout his army career, concentrating particularly on thermodynamics and inventing several devices relating to heat retention. Thompson was knighted in 1784 and created Count Rumford in the nobility of the Holy Roman Empire in 1792. With Sir Joseph Banks he established the Royal Institution of Great Britain in 1799, and he endowed a professorship at Harvard University. In later life Sir Benjamin settled in Paris. Sarah Thompson having died in 1792, he married Antoine Lavoisier's widow, Marie-Anne, as his second wife in 1804, but they separated a few years later. He continued his scientific work until his death in 1814.
