Halley's Comet has been prominently displayed in many newspapers during the last few months. For the first time in 76 years it appeared this winter, the nocturnal sky. This is an appropriate occasion to clearly visible against point out the fact that Sir Edmund Halley also constructed the world's first life table in 1693, thus creating the scientific foundation of life insurance. Halley's life table and its successors were viewed as deterministic laws, i. e. the number of deaths in any given group and year was considered to be a well defined number that could be calculated by means of a life table. However, in reality this number is random. Thus any mathematical treatment of life insurance will have to rely more and more on probability theory.
