i feel fairly sure that she didn't write Superman, but I do know that she wrote supermEn. She moved to NYC when the Fleicher studio became Famous, circa late 1945. She then (I believe) worked for Binder shop, where she wrote a few of the superhero titles that they did for Nedor-Standard-Pines (Fighting Yank, I think). I understand she later did work for Marvel. I do not believe she worked for DC. This was the age before credits,and the only stories with her name on them were text pieces.
