12759 Joule           Discovered 1993 Oct. 9 by E. W. Elst at the European Southern Observatory.
James Joule (1818-1889) was an English physicist who attempted to demonstrate the unity of forces in nature. In 1840 he determined the mechanical equivalent of heat and showed that heat is produced by motion.
