Zimmer attended Queens Vocational High School, the Central High School of Needle Trades, and the Harlem Evening High School. Supporting herself as a dental assistant, she then took classes at the Fashion Institute of Technology (FIT) and studied costuming with the New School of Social Research Dramatic Workshop, led by Erwin Piscator. Later, while living in New York in the 1940s and 1950s, she variously worked in toy design and doll clothing, in early television with the Bil Baird puppets, and in summer theater at the Camp Tamiment Playhouse.[citation needed]
