Judith Masur was born on February 22, 1946 in Manhattan, New York. She was raised in Yonkers with her brother, the actor Richard Masur. From the age of five, she began drawing, which sparked a lifelong passion for art.
As a child, she enjoyed acting on stage but did not have the ability to memorize her lines. She was a high-achieving student who was selected for the prestigious Columbia Science Honors Project at Columbia University. She then went to Bryn Mawr College, where in 1966 she witnessed homophobic injustice from the college Deans, which radicalized her personal politics but also led to feelings of disillusionment with the college. Still, she graduated two years later, followed by a period of living overseas in Italy. From here, she embarked on many jobs, including selling gloves in the open market in Florence.
In 1976, Judith moved to San Francisco and started writing and performing at Mothertongue Readers Theater. She then went on to co-found Fat Lip Readers Theater – which runs to this day – and the Jewish Lesbian Writers Group. In San Francisco she started hand-drawing posters and flyers, drawing the logo for the Jewish Lesbian Forum, as well as a cover for one of Judith Stein’s A New Haggadah: A Jewish Lesbian Seder. She was also responsible for Big Woman Notecards, a series of greetings cards that celebrates body positivity. The cards, which started as black and white line drawings, were first distributed by hand at the Michigan Women’s Music Festival, then eventually all over the country.
In 1976, Judith came out after her first lesbian seder, after which she started a relationship with her first girlfriend. In 1977, she attended the 1977 Feminist Forum, after which she started volunteering at the San Francisco Women’s Building. She also attended two Jewish Feminist Conferences and helped with the rise of the Jewish lesbian movement. In 1980, she started teaching Italian to Jewish feminist lesbian therapist and writer Jessica Barshay, and a year later they started a relationship.
In the early 80s, she and Judy Freespirit co-founded the San Francisco Bay Jewish Lesbian Writers Group, for which she designed the flyers. Towards the end of the 80s, she attended a twenty-year reunion at Bryn Mawr College, where she successfully campaigned for the college to accept its large number of out lesbian alumni and increase visibility for the college’s lesbian students.
In 1998, Judith and Jessica’s 18-year relationship ended when Jessica died by suicide, after a long period of illnesses. After Jessica’s death, Judith started taking lessons in film editing at community college. In 2004, Judith released the highly-rated Hearts Cracked Open, a film exploring lesbian tantra.
Judith has donated extensive archives to the Lesbian Herstory Archives in New York, the Bryn Mawr College Special Collections in Pennsylvania and the Bay Area Lesbian Archives in California. Her collections include a selection of her posters, flyers, films and writing relating to lesbian activism since the 1960s.
