Karl F. Sundman

Karl Frithiof Sundman (28 October 1873, in Kaskinen – 28 September 1949, in Helsinki) was a Finnish mathematician[1] who used analytic methods to prove the existence of a convergent infinite series solution to the three-body problem in two papers published in 1907[2] and 1909.

[3] His results gained fame when they were reproduced in Acta Mathematica in 1912.

Sundman was awarded the Pontécoulant prize by the French Academy of Science in 1913 for his work on the 3-body problem.

[6] The crater Sundman on the Moon is named after him, as is the asteroid 1424 Sundmania.
