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.
