Edward Sang

Edward Sang was born in Kirkcaldy in 1805. At the age of only 13, he enrolled at the University of Edinburgh, where he enrolled in the second mathematics class because there was no advanced class that year. He embarked on a career as mathematician, teacher, surveyor, civil engineer and actuary, and was elected a member of the Royal Society of Edinburgh. From 1841 to 1843 he was Professor of Mechanical Sciences at Manchester New College, from where he went to Constantinople to plan railways and engineering projects for the Sultn Abdul-Mejid, and lectured in Turkish to students at the Imperial School. After returning to Edinburgh in 1854, he published numerous mathematical and related books and papers. His best-known achievement was to prepare, with the assistance of his daughters Flora and Jane, tables of logarithms of up to 28 figures for numbers up to 370,000! He also invented a lantern which was the model for Alan Stevenson's Skerryvore Lighthouse. Edward Sang died in Edinburgh 1890. Sang and his wife Isabella Elmslie had a son and four daughters, all of whom died unmarried.
