Born in Austria in 1895, and lived in Vienna during her youth. Studied under Michael Powolny at the Kunstgewerbeschule in Vienna. Established her own studio at Grunbach in 1925. By the late 1920s Singer was a major European ceramic artist. Her work appeared at the Austrian exhibition at the 1925 Paris International Exposition, and at many other international expositions including London in 1934 and Brussels in 1935. She left Austria to move to Pasadena, California, in 1939. In California she established her own studio and continued to produce figural ceramic sculpture. She began exhibiting her work in America in 1939, and she won a Fine Arts Foundation grant in 1946 to produce a number of sculptural pieces for Scripps College. Her work is considered significant due to her link between the sculptural ceramic movement in Europe and America. Singer spent her life in a wheelchair, and was a victim of post-World War I malnutrition.
