Suzy Lorraine Heitler Ehrlich was born in New York in 1919. She began taking drawing classes in the late 1940s at the Art Students League, where she met her future husband, Sol Ehrlich. During the 1950s and 1960s, Ehrlich's illustrations appeared in Women's Wear Daily, Look, and Life magazines. She also created illustrations for sewing and pattern publications. Ehrlich worked as a freelancer from a home studio, employing models wearing garments sent to her by clients.
Ehrlich returned to the classroom during the 1960s to study illustration with Jack Potter, a charismatic and talented instructor at the School of Visual Arts. Potter was noted for teaching a course titled “Drawing and Thinking" and had a great influence on Ehrlich's work. She was also inspired by the work of Peter Max. Ehrlich also taught drawing classes in her home and in her later years worked for the Metropolitan Museum of Art in production, designing objects for their gift store.
Suzy Lorraine Ehrlich died March 2, 2006 in New York City, where she had lived her entire life.
