Page, Charles (Grafton) (1812–68) physician, inventor; born in Salem, Mass. A Harvard graduate and a trained physician, he practiced medicine, and, in his free time, experimented with electricity. Among his many contributions were a self-acting circuit breaker and a primitive electric locomotive, which had a trial run in 1850. In 1841 he became one of two principal examiners of the U.S. Patent Office. He resigned in 1852, but returned to the patent office in 1861 and remained there until his death.
