Sophy Pollak Regensburg (1885 – April 6, 1974) was an American naïve painter.
Born in New York City,[1] Regensburg was a member of a prominent family; her brother, Walter Pollak, sat on the New York Stock Exchange.[2] She was married to cigar maker Melville E. Regensburg, with whom she had three children, until his death.[3] Active during her marriage as a volunteer, she took up painting in widowhood, when her physician suggested she needed to slow down;[1] she had studied under William Merritt Chase and Robert Henri at the New York School of Art.[2] In 1952, the first year in which she was involved in the hobby, she won a gold medal in the National Amateur Painters Competition; she would go on to present work in thirteen one-woman shows and fifteen group exhibits before her death. She produced mainly still lifes.[3] Her work is represented in the collections of the American Folk Art Museum,[4] the Miami University Art Museum,[1] and Smith College.[5]
