Gae Foster (born 1903) was from Bunker Hill, California. By age 17 she was already dancing with Fanchon and Marco in vaudeville and presentation houses. By 1925 she was assisting Fanchon in organizing dance choruses for cinema prologues. By 1928, while still working for Fanchon and Marco, she was sending out her own unit, Gae Foster’s Sweet Sixteen. By 1933 she was dance director at the Roxy Theater in New York, where she created the Roxyettes, a.k.a the Gae Foster Girls, similar to the Rockettes, but renowned for their tricks, performing routines on roller skates, pogo sticks, unicycles, and the like. The troupe performed in ten Hollywood films between 1938 and 1940. Foster also choreographed musical numbers for Olsen and Johnson’s Hellzapoppin (1938-1941), and the Betty Grable movie Pin-Up Girl (1944).
