Source-derived summary

Raghu Raj Bahadur (30 April 1924 – 7 June 1997) was an Indian statistician considered by peers to be "one of the architects of the modern theory of mathematical statistics".

Biography

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 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. He was a cousin to Madhur Jaffrey.

Contributions

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. He was the President of the Institute of Mathematical Statistics during 1974–75 and was elected a Fellow of the American Academy of Arts and Sciences in 1986.

Editorial summary

The public source identifies “Raghu Raj Bahadur” as indian-American mathematician. This brief keeps that definition visible, then builds a research path around Raghu, Bahadur and Indian-American.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1924, 1997, 1943, 1945—that can be checked directly. The linked authority record independently contributes the date 1924-04-30. Its value is orientation rather than verdict, with Raghu, Bahadur and Indian-American providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Raghu Raj Bahadur”, the useful work is to connect “indian-American mathematician” to the records capable of establishing context and consequence.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q1245339. VIAF identifies the subject as 24681035. The Library of Congress control number is n89241270. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1924, 1997, 1943 and 1945.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
