Berthold Bodenheimer - Berthold’s 2nd (or possibly 3rd?) wife?

Berthold was my grandfather. His 1st wife (she may have actually been his 2nd wife), Marta, was my grandmother and she was murdered in Auschwitz.
Berthold came to the US in 1937 and was married again (likely in the early 1940’s). Her name was Emma Bender. I have been unable to locate the marriage certificate, but just looking for date of marriage for genealogical purposes.
