caption_attribution_description: English: Robert A. Millikan Memorial Library — at Caltech, Pasadena. The tallest building on the Caltech campus.
context_page_description: Caltech's 124-acre primary campus is located in Pasadena, California, approximately 11 miles northeast of downtown Los Angeles. It is within walking distance of Old Town Pasadena and the Pasadena Playhouse District and therefore the two locations are frequent getaways for Caltech students.
  In 1917 Hale hired architect Bertram Goodhue to produce a master plan for the 22 acres campus. Goodhue conceived the overall layout of the campus and designed the physics building, Dabney Hall, and several other structures, in which he sought to be consistent with the local climate, the character of the school, and Hale's educational philosophy. Goodhue's designs for Caltech were also influenced by the traditional Spanish mission architecture of Southern California.
  During the 1960s, Caltech underwent considerable expansion, in part due to the philanthropy of alumnus Arnold O. Beckman. In 1953, Beckman was asked to join the Caltech Board of Trustees. In 1964, he became its chairman. Over the next few years, as Caltech's president emeritus David Baltimore describes it, Arnold Beckman and his wife Mabel "shaped the destiny of Caltech".
