Majumdar was born on 1 March 1904 in Patgram, a village in
Dacca district of the
Bengal Presidency, now in
Bangladesh. His father, Mahesh Chandra Majumdar worked in a tea estate in Jalpaiguri district of
West Bengal. He had his schooling in Jalpaiguri. After completing his undergraduate studies at
Rajshahi College, he went to
Calcutta to study for his master's degree in physics. Majumdar studied physics at
Calcutta University in the laboratory of
B. B. Ray, where he carried out an experiment that demonstrated the
Raman effect in X-rays; this was published in
Nature in 1931. After completing his Master's in 1927, he moved to
Allahabad University, where he wrote a research paper with
Meghnad Saha. For the rest of his career, he concentrated on
theoretical physics. With Saha's encouragement, he went abroad for his doctoral studies and obtained his Ph.D. from the
University of Jena. During this period, he was a frequent visitor to
Cambridge University, where his friend and collaborator
Daulat Singh Kothari was working for his Ph.D. According to one source, Majumdar went to Cambridge, "arriving — it is said — on the doorstep of Lord Rutherford's home on a Sunday afternoon". == Career ==
