Harald Cramer was a Swedish mathematician, actuary and statistician, born on 25 September 1893 and died on 5 October 1985. He specialized in mathematical statistics and in probabilistic number theory, the use of probability to study the behaviour of integers. John Kingman described him as one of the giants of statistical theory. Actuarial science applies probability and statistics to insurance and pensions, so his three named specialities, actuarial work, statistics and probabilistic number theory, all rest on the mathematics of chance.
