Bahadur was born in Delhi, India, and received his BA (1943) and MA (1945) in mathematics from St. Stephen’s College, University of Delhi . He received his doctorate from the University of North Carolina under Herbert Robbins in 1950 after which he joined University of Chicago.

He published numerous papers and is best known for the concepts of "Bahadur efficiency" and the Bahadur–Ghosh–Kiefer representation (with J. K. Ghosh and Jack Kiefer).

He also framed the Anderson–Bahadur algorithm along with Theodore Wilbur Anderson which is used in statistics and engineering for solving binary classification problems when the underlying data have multivariate normal distributions with different covariance matrices.

Legacy He held the John Simon Guggenheim Fellowship (1968–69) and was the 1974 Wald Lecturer of the IMS.
