Additionally, contemporary art writer and scholar Dave Hickey, in his 2004 exhibition at the Otis College of Art and Design, christened Feitelson and the other Hard Edge painters as The Los Angeles School.

Lorser Feitelson’s works are included in the permanent collections of the Los Angeles County Museum of Art; the National Museum of American Art; Smithsonian Institution, Library of Congress and National Gallery of Art, Washington D.C.; the San Francisco Museum of Modern Art; the Whitney Museum of American Art, Museum of Modern Art and Brooklyn Museum of Art, New York; Columbus Museum of Art; and numerous other public and private collections.
Separating from Hord, she moved to Los Angeles in 1934, joining the post-surrealist group around Lorser Feitelson and Helen Lundeberg, and participating in the mural division of the Federal Arts Project, where she learned the art of screenprinting, which would become her favored graphic technique.
In the late 1950s, Langsner and Peter Selz, then professor at the Claremont Colleges, observed a common link among the recent work of John McLaughlin (1898–1976), Lorser Feitelson (1898-1978), Karl Benjamin (1925-2012), Frederick Hammersley (1919–2009) and Feitelson's wife Helen Lundeberg (1908-1999).
This was called, simply, California Hard-edge painting. Included in this show were Florence Arnold, John Barbour, Larry Bell, Karl Benjamin, John Coplans, Lorser Feitelson, Frederick Hammersley, June Harwood, Helen Lundeberg, John McLaughlin, and Dorothy Waldman.
From 1980-1990 she studied figure drawing with Harry Carmean at Art Center College of Design in Pasadena and exhibited at the Tobey Moss Gallery in Los Angeles with Lorser Feitelson and Helen Lundeberg.
