During the mid to late 20th century, several colleges named buildings, physical features, awards, and professorships after Millikan. In 1958, Pomona College named a science building Millikan Laboratory in honor of Millikan. After reviewing Millikan's association with the eugenics movement, the college administration voted in October 2020 to rename the building as the Ms. Mary Estella Seaver and Mr. Carlton Seaver Laboratory.
