Mathematician:Georg Mohr

Born Jørgen Mohr, latinised as Georg(ius) Mohr.

Danish mathematician and geometer now famous for proving in 1672 that any geometrical construction that can be made with compasses and straightedge can also be achieved by using only compasses. This result was overlooked at the time. Lorenzo Mascheroni made the same discovery in 1797. However, it was only in 1928 that Mohr's priority came to light.

Other books of his are rumoured but none have come to direct light.
