Mayer, Julius Robert von (1814-78), German philosopher, was born at Heilbronn. He studied medicine at Tubingen, Munich, and Paris, and, after some experience as a ship's surgeon, he settled down to practise in Heilbronn in 1841. In 1842 he published The Mechanical Theory of Heat, and in 1848 advocated the meteoric origin of the sun's heat. His writings have been collected.
