Nikolaus Mercator (actually: Nikolaus Kauffman , * between 1619 and 1623, but probably 1620 with Cismar or in Eutin ; † January 4 or 14 or February 12, 1687 in Paris ) was a mathematician and astronomer who worked on logarithms got known.
He studied in Rostock and Leiden and was a lecturer in Rostock from 1642 to 1648, then in Copenhagen from 1648 to 1654 . From there he went to Paris (1655–1657). In 1657 he moved to England and lived in London from 1658 to 1682 . Here he built a pendulum clock that allowed more precise time measurements at sea to determine the degree of longitude . For this he was admitted to the Royal Society in 1666 . In 1682 he went to France again. He built the Versailles fountains and died there in 1687.
Mercator also dealt with pure tuning and describes that by dividing the octave into 53 parts you can create a scale in almost exact natural tuning, which allows unlimited modulation. See: The division of the octave into 53 parts .
