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.

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.
