Thank you for the great post. I'd like to add a few more important events, related to the electric fan:

1.) 1904 – Philip H. Diehl invents the first oscillating fan
2.) 1910 – electric fans are used in households
3.) 1920 – electric fans are used in commercial buildings
1933 – Silver Swan appears with a radically elegant design
4.) 1940 – The Packard is the first car to offer optional “factory air” in a vehicle

The story of the electric fan is really interesting. There are fans in so many homes and industries but a few people know how it all started :)
