The First Logarithmic Table Produced by a Calculating Machine (1875)


In 1875 Swedish inventor Martin Wiberg used his difference engine to produce Tables de Logarithms Calculées et Imprimées au Moyen de la Machine à Calculer du M. Wiberg. This set of tables of seven-place logarithms from 1 to 100,000 was the first logarithmic table produced by a calculating machine. The device is preserved at Tekniska museet (The Technical Museum) of Sweden in Stockholm.
