12, 1925. Under UC President William Wallace Campbell, enrollment at the Southern Branch expanded so rapidly that by the mid-1920s the institution was outgrowing the 25 acre Vermont Avenue location. The Regents searched for a new location and announced their selection of the so-called "Beverly Site"—just west of Beverly Hills—on March 21, 1925, edging out the panoramic hills of the still-empty Palos Verdes Peninsula. After the athletic teams entered the Pacific Coast conference in 1926, the Southern Branch student council adopted the nickname "Bruins", a name offered by the student council at UC Berkeley. On February 1, 1927, the Regents renamed the Southern Branch the University of California at Los Angeles (the word "at" was officially replaced by a comma in 1958, in line with other UC campuses). In the same year, the state broke ground in Westwood on land sold for $1 million, less than one-third its value, by real estate developers Edwin and Harold Janss, for whom the Janss Steps are named. The campus in Westwood opened to students in 1929. The original four buildings were the College Library (now Powell Library), Royce Hall, the Physics-Biology Building (which became the Humanities Building and is now the Renee and David Kaplan Hall), and the Chemistry Building (now Haines Hall), arrayed around a quadrangular courtyard on the 400 acre (1.6 km2) campus. The first undergraduate classes on the new campus were held in 1929 with 5,500 students. After lobbying by alumni, faculty, administration and community leaders, UCLA was permitted to award the master's degree in 1933, and the doctorate in 1936, against continued resistance from UC Berkeley. Maturity as a university During its first 32 years, UCLA was treated as an off-site department of UC. As such, its presiding officer was called a "provost", and reported to the main campus in Berkeley. In 1951, UCLA was formally elevated to co-equal status with UC Berkeley, and its presiding officer Raymond B. Allen was the first chief executive to be granted the title of chancellor. The appointment of Franklin David Murphy to the position of Chancellor in 1960 helped spark an era of tremendous growth of facilities and faculty honors. By the end of the decade, UCLA had achieved distinction in a wide range of subjects. This era also secured UCLA's position as a proper university and not simply a branch of the UC system. This change is exemplified by an incident
