He received his doctorate from the University of North Carolina under Herbert Robbins in 1950 after which he joined University of Chicago. He worked as a research statistician at the Indian Statistical Institute in Calcutta from 1956 to 1961. He spent the remainder of his academic career in the University of Chicago.[3] ContributionsHe published numerous papers[4] and is best known for the concepts of "Bahadur efficiency"[5] and the Bahadur–Ghosh–Kiefer representation (with J. K. Ghosh and Jack Kiefer)[6] He also framed the Anderson–Bahadur algorithm[7] 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. LegacyHe held the John Simon Guggenheim Fellowship (1968–69)[8] and was the 1974 Wald Lecturer of the IMS.[2] He was the President of the Institute of Mathematical Statistics during 1974–75[8] and was elected a Fellow of the American Academy of Arts and Sciences in 1986.[9] References1. ^{{cite web | url=http://chronicle.uchicago.edu/970612/bahadur.shtml | title=Obituary: Raghu Raj Bahadur, Statistics | work=The University of Chicago Chronicle | date=12 June 1997 | accessdate=8 October 2018 }} 2. ^1 2 {{Cite journal|title=Raghu Raj Bahadur|url=http://www.oxfordreference.com/view/10.1093/oi/authority.20110803095440927|publisher=Oxford Reference|accessdate=17 June 2013}} 3. ^{{Cite newspaper|last=Marcano|first=Tony|title=R.
