History 1947 Founded in 1947 by Dr. Vikram A. Sarabhai, the Physical Research Laboratory (PRL) had a modest beginning at his residence, the RETREAT, with research on Cosmic Rays. 1947 The Laboratory was formally established on November 11, 1947, in the M. G. Science College, Ahmedabad, with support from the Karmkshetra Educational Foundation and the Ahmedabad Education Society. The initial focus was research on Cosmic Rays and the properties of the Upper Atmosphere. Research in Theoretical Physics and Radio Physics were added later with grants from the Atomic Energy Commission. 1950 Formation of First Council of Management with following members : Dr. S. S. Bhatnagar, FRS Dr. K. S. Krishnan, FRS Dr. Y. G. Naik Dr. V. A. Sarabhai Dr. K. R. Ramanathan 1951 First Ozone Measurement Station at Mt. Abu 1952 Foundation of PRL Campus laid by Sir C.V.
