Joint Life Commutation Columns and Rates Copright 1912, by Isidore P. Mantz, Consulting Actuary
For combinations of 2,3,4,5 and six lives.

This book isn’t reading material, it’s primarily a book of tables of D(x), M(x), S(x) and so on. Numbers like these are used by actuaries to end up with q(x) which is the probabilty of dying at age x. q(x) is then used in formulating the price of life insurance. So if you’re looking for joint life tables from the early 1900’s, you’ve come to the right place!

Also of interest is the introduction on Construction of Mortality Tables. It’s three pages that discusses how the tables were calculated – and it would seem that the procedure has changed little over the the intervening 100 years.
