This is Marilyn Monroe's mother, Gladys Baker. She suffered from mental illness from the time Norma Jeane was born. As a result, her daughter was forced to live in several foster homes throughout her entire childhood.
Here she is at 14 years old. After her aunt got sick, she had to move in with the Goddard family. She lived there previously, where she was sexually abused at age 11 by her legal guardian, Erwin Goddard.
A lot of famous folks have unglamorous first jobs. Norma Jeane was no exception. Here she is posing for a picture while working at a munitions factory. She was asked to take this and several other pictures after being spotted by an Army propaganda officer.
