In 1930, Lundeberg graduated from Pasadena Junior College. She enrolled in art classes at the Stickney Memorial Art School in Pasadena, where she met professor and fellow painter Lorser Feitelson. Feitelson's dynamic approach to composition and broad ranging interests in the international art scene inspired Lundeberg. In conversation with Fidel Danieli, as part of the UCLA Oral History Project in 1974, Lundeberg explained, "When Lorser came and began to explain things, to make diagrams and to give us principles of different kinds of construction – light dawned! It was really very exciting."
