Sang was born in Kirkcaldy and, although he is known primarily for his exhaustive computation of logarithms and other mathematical tables (some of them to 28 places), he was a man of many talents, particularly in engineering design. He studied in Edinburgh under John Leslie and later acted as his assistant. In 1847 he went to Constantinople to teach mathematics and natural philosophy and helped to establish a school of civil engineering and to design railroads, an iron works and other projects. Returning to Edinburgh in 1854 he became the first official Lecturer at the Faculty of Actuaries. There he laid the foundation of scientific study for the Scottish school of actuaries and is remembered for such tables of actuarial functions as Life Assurance and Annuity Tables for every Combination of Two Lives.
