Of the birth, parentage, education, and family life of Joshua Milne, one of the great names in the history of actuarial science, very little is now known. He became actuary to the Sun Life Assurance Society in 1810 and published, in 1815, a landmark work entitled A Treatise on the Valuation of Annuities and Assurances, which revolutionized the whole business of life insurance. Milne became such an authority in his field that he was invited, in 1825 and again in 1827, to testify before a parliamentary select committee looking into laws respecting friendly societies. His long service to Sun Life came to an end with retirement in 1843, and he died at Upper Clapton in 1851.
