Georg Mohr

Jørgen Mohr (Latinised Georg(ius) Mohr; 1 April 1640 – 26 January 1697) Beginning in 1662 he traveled to the Netherlands, to study mathematics with Christiaan Huygens. In 1672 he published his first book, Euclides Danicus, simultaneously in Copenhagen and Amsterdam, in Danish and Dutch respectively. This book, proving the Mohr–Mascheroni theorem 125 years earlier than Lorenzo Mascheroni, would languish in obscurity until its rediscovery in 1928. Mohr served in Franco-Dutch War in 1672–1673, and was taken prisoner by the French. As well as his work on geometry, Mohr contributed to the theory of nested radicals, with the aim of simplifying Cardano's formula for the roots of a cubic polynomial. In 1695 he took a job with Tschirnhaus,
