Person: Chowla, Sarvadaman
Sarvadaman Chowla was a Britishborn Indian American mathematician, specializing in number theory.
Mathematical Profile (Excerpt):
 It was during the visit to England that Sarvadaman Chowla was born.
 At the age of 21 Chowla was awarded his master's degree from Government College in Lahore.
 After returning to India, Chowla was appointed professor of mathematics at St Stephen's College in Delhi, then at Benares Hindu University in Benares, then at Andhra University in Waltair, and finally at Government College of Punjab University in Lahore where he was Head of the Department of Mathematics from 1936 to 1947.
 This period while Chowla was Head of Mathematics at Lahore was a very difficult one.
 The Punjab, where Chowla worked, was in one of the most difficult positions being a Muslim majority province with a large Sikh community that had become antiMuslim.
 Chowla was in Lahore which the Indian Independence Act put in Pakistan, close to the new border with India.
 There Chowla became a visitor at the Institute for Advanced Study in Princeton, where he remained until the autum of 1949 when he was appointed as professor at the University of Kansas at Lawrence.
 After three years at the University of Kansas, Chowla moved to the University of Colorado at Boulder where he remained until 1963.
 Chowla produced a remarkably rich research output, and his results in many of areas of number theory and combinatorics are of the greatest significance.
 Among the theorems to which Chowla's name have been attached are the BruckChowlaRyser theorem on designs (1950); the AnkenyArtinChowla theorem on the class number of real quadratic number fields (1952); the ChowlaMordell theorem on Gauss sums (1962); and the ChowlaSelberg formula for the product of certain values of the Dedekind eta function.
 Among the many honours given to Chowla were the Padmabhushan Award from the Indian National Academy of Sciences, to which he had been elected a member; and an honorary membership of the Royal Norwegian Society of Sciences and Letters.
Born 22 October 1907, London, England. Died 10 December 1995, Laramie, Wyoming, USA.
