At the time of Munk's return to Scripps, it was still under the administration of UCLA, as it had been since 1938. It became part of the University of California, San Diego (UCSD) when that campus was founded in 1958. Revelle, its director at the time, was a primary advocate for establishing the La Jolla campus. At this time Munk was considering offers for new positions at the Massachusetts Institute of Technology and Harvard University, but Revelle encouraged Munk to remain in La Jolla. Munk's founding of IGP at La Jolla was concurrent with the creation of the UCSD campus.
