The first life table was written by Edmund Halley in 1693, but it was only in the 1750s that the necessary mathematical and statistical tools were in place for the development of modern life insurance. James Dodson, a mathematician and actuary, tried to establish a new company aimed at correctly offsetting the risks of long term life assurance policies, after being refused admission to the Amicable Life Assurance Society because of his advanced age. He was unsuccessful in his attempts at procuring a charter from the government.
