Gerhard Christoph Hermann Vechtmann (10 April 1817 – 2 August 1857) was a German mathematician, who is best known for his work on lemniscates.
Vechtman was born in Wittmund in the northern part of the Kingdom of Hanover in Germany, where his father worked as a preacher.
In Göttingen he became a member of the pedagogic seminar (institute for teacher education) and taught at the local gymnasium until he was appointed Hofmeister at the Ritterakademie in Lüneburg in 1841.
In 1843 he handed in his dissertation De curvis lemniscatis at the University of Göttingen and was awarded a Doctor of Philosophy.
[1][2] In his dissertation De curvis lemniscatis he examined the lemniscate of Bernoulli and discovered a surprising property of certain angles occurring in it.
