Else Blangsted, who fled Nazi Germany as a teenager, believing that she had given birth to a stillborn child, then built a career as a leading music editor on Hollywood films, died May 1 in Los Angeles. She was 90.

For more than 30 years, Ms. Blangsted played a major part in shaping how movie music was heard in features like “The Color Purple,” “Tootsie,” and “On Golden Pond.”

She concealed a teenage pregnancy when her family sent her to a Jewish boarding school in Switzerland to escape the Holocaust. The pregnancy was discovered when she went into labor. Under sedation during the delivery, she was told afterward that the child had died. Fifty years later, she discovered that her daughter had survived and was adopted by German-speaking Jews. When they finally met, “it was the end of drama, the end of shame, the end of accusations, the end of migraines,” Ms. Blangsted said.
