Marilyn Monroe was born as Norma Jeane Mortenson or Norma Jeane Baker, on June 1, 1926 in Los Angeles, California, United States. When she was seven years old, her mother, Gladys (Monroe) Baker Mortenson, was hospitalized after being diagnosed as a paranoid schizophrenic, a severe mental condition. Norma was left in a series of foster homes and the Los Angeles Orphans' Home Society. The constant move from one foster home to another resulted in Norma's "sketchy" educational background.
