Personal life
He was born on 28 October 1911 in a Sikh Gill Jat family in a village in Hoshiarpur district of Punjab. He attended Khalsa High School in Mahilpur (1928) and left for America in 1929. He attended and graduated with a bachelor's and master's degrees from University of Southern California. He worked for his PhD in Physics at University of Chicago under the supervision and guidance of Arthur Compton, the Nobel Prize winning scientist. He received his PhD in March 1940. He was a good friend and close colleague of Homi J. Bhabha, who offered him the research fellow professorship at Tata Institute of Fundamental Research in 1947.
He was a close friend of Nehru, who was impressed with his scientific breakthroughs. Nehru offered him the post of Officer-on-Special Duty (OSD) with the Atomic Energy Commission in New Delhi; he asked him to become the first Director of Central Scientific Instruments Organization (CSIO) of India.
He as its Director established (CSIO) as a leader in advanced scientific instrument design in Asia. Gill was a key advisor and planner to Nehru on India's nuclear weapons strategy in the 1950s-1960s.
Robert Oppenheimer was a close colleague and friend who he worked with on the Manhattan project. Oppenheimer asked Gill to present a paper at the California Institute of Technology at a conference arranged to celebrate the 80th birthday of Professor Robert Millikan, winner of the 1928 Physics Nobel Prize.
