Your old tabletop fan can be traced back to German-American inventor Philip Diehl, who invented the electric ceiling fan when he worked for the Singer Company. He took a motor from a sewing machine and mounted it to the ceiling with blades. After several iterations, the oscillating fan was born. The first electric fan for household use was introduced by Westinghouse in 1910.
