Thorvald Nicolai Thiele (24 December 1838 – 26 September 1910) was a Danish astronomer and director of the Copenhagen Observatory.[1] He was also an actuary and mathematician, most notable for his work in statistics, interpolation and the three-body problem.

Thiele was the first to propose a mathematical theory of Brownian motion,[2] introduced the cumulants and likelihood functions, and was considered to be of the greatest statisticians of all time by Ronald Fisher.[3] In the early 1900s he also developed and proposed a generalisation of approval voting to multiple winner elections called Sequential proportional approval voting,[4] which was briefly used for party lists in Sweden when proportional representation was introduced in 1909.

Thiele also was a founder and Mathematical Director of the Hafnia Insurance Company and led the founding of the Danish Society of Actuaries. It was through his insurance work that he came into contact with fellow mathematician Jørgen Pedersen Gram.

Thiele was the father of astronomer Holger Thiele.

The main-belt asteroids 843 Nicolaia (discovered by his son Holger) and 1586 Thiele are named in his honour.[1]
