Shirley Estelle Witebsky Reddy, sculptor and printmaker, was born in Minneapolis, Minnesota on August 31, 1925. She studied art and printmaking at the University of Minneapolis, graduating in 1945.

Around 1952, Witebsky left for France to study with Stanley William Hayter at Atelier 17. In Paris, she met fellow printmaker Krishna Reddy who was also working at the atelier; they were later married. They returned to the United States and, in 1964, were both invited to participate in the first International Sculpture Symposium in North America, which took place in Montreal, Canada. Witebsky was the only female artist invited to participate in the event. Both she and Reddy each created a sculpture for the Mount-Royal Park, at which the works can still be found. (Of note: because Witebsky is represented in this sculpture park, she is listed as a Canadian artist on some websites.)

After being diagnosed with cancer, Witebsky returned to Minneapolis for a short time before moving to Tenafly, New Jersey for treatment. She succumbed to the disease in late August of 1965, just short of her forty-first birthday.

Witebsky's graphic work was sometimes sold through Roten Galleries, which sold original prints at universities throughout the United States from around 1941 through the mid 1970s. The work of Shirley Estelle Witebsky is represented in the collections of the Brooklyn Museum, New York; the Oregon State University, Corvallis; the Flint Institute of Arts Museum, Michigan; the British Museum, London; the California State University at Long Beach; the Bureau d'Art Public, Ville de Montreal, Canada; the Musée d'Art Moderne de Paris, France; the Western New Mexico University, Silver City; and the National Gallery of Art, Washington, D.C.
