"In the early 1930s, the Phillips head screw was invented by Oregon businessman Henry Phillips (1889–1958). Automobile manufacturers now used car assembly lines. They needed screws that could take greater torque and could provide tighter fastenings. The Phillips head screw was compatible with the automated screwdrivers used in an assembly line."
There are interesting articles on the development of the torx fastener. Most fastener head development in the US appears to be in response to the industrial development of automobile assembly and the need to specific torque and other tolerances.
