Late Night TCM Note Regarding Mary Hisgen

I was watching TCM late - very late - last night, when they presented a frivolous musical short film: Henry Santry and his Soldiers of Fortune. It was a group of musicians dressed as soldiers singing songs. Then, came on an amazing dancer - remarkably limber - who performed, essentially, as a clown. Apparently her name was Mary Hisgen: a true talent! But she never made it big, apparently. Just another remarkable person in the performing arts; a blooming flower who must have been clobbered by the Great Depression. Not much on the Internet about her. Someone should write her biography (1910 - 2006, apparently).
