On this date in 1901 King Gillette introduced the safety razor. Before his success with cheap disposable blades, men shaved with one of those creepy straight-edge Sweeney Todd razors. After the money started rolling in, Gillette built a big house in Palm Springs and had celebrity architect Wallace Neff design a huge mansion near Calabasas. When he died in 1932 his wife sold the compound to film director Clarence Brown who sold it to Bob Hope, who gave it to a bunch of nuns. A succession of religious institutions had the land until the Santa Monica Mountains Conservancy opened its 588 acres as a park in 2007. The Conservancy offers nature tours, historic talks, and even a survival class! Will you need a straight razor to survive in the wilderness? Go to the ranch and find out.
