Hedy Lamarr and Philco
#1

My wife was watching a documentary on Hedy Lamarr last night (on PBS).  Turns out she was both an inventor and an actress.  She is credited with inventing a jam proof guidance system for torpedoes.   She says she got the idea from playing with a Philco with a mystery control.  A Mystery control philco was featured in the show.  Is this old Philco trivia?
