Johann Faulhaber

Johann Faulhaber (5 May 1580 to 10 September 1635) was a German mathematician, specifically a calculator or Rechenmeister, born in Ulm. A trained weaver, he became surveyor of the city of Ulm and worked as a fortification engineer in Basel and Frankfurt and under Maurice, Prince of Orange, in the Netherlands. He collaborated with Johannes Kepler and Ludolph van Ceulen and made the first publication of Henry Briggs's logarithms in Germany. His major contribution was in calculating the sums of powers of integers, the standard formula for which is now called Faulhaber's formula and which Jacob Bernoulli cites in the Ars Conjectandi. He also wrote on alchemy, astrology and numerology, belonged to the Rosicrucians and published prophecies after the Great Comet of 1618.
