Philip H. Diehl (29 January 1847 – 7 April 1913) was a German-American engineer and inventor who held several U.S. patents, including electric incandescent lamps, electric motors for sewing machines and other uses, and ceiling fans. Diehl was a contemporary of Thomas Edison and his inventions caused Edison to reduce the price of his incandescent bulb.
The electric fan was invented in 1882 by Schuyler Skaats Wheeler. A few years later, Philip Diehl mounted a fan blade on a sewing-machine motor and attached it to the ceiling, inventing the ceiling fan, which he patented in 1887. Later, he added a light fixture to the ceiling fan. In 1904, his Diehl and Co. added a split-ball joint, allowing it to be redirected; three years later, this developed into the first oscillating fan.
