According to Wikipedia: "The cloche hat or simply cloche is a fitted, bell-shaped hat for women that was invented in 1908 by milliner Caroline Reboux. They were especially popular from about 1922 to 1933.Its name is derived from cloche, the French word for "bell".

Interestingly it was designed to be worn low on the forehead, with the wearer's eyes only slightly below the brim.
Looking at historical references, it seems to come into vogue every 20 years or so ... and right now it appears to be having a re-resurgence.
