Willem Abraham Wythoff (Dutch pronunciation: [ˈʋɪləm ˈaːbraːɦɑɱ ˈʋɛithɔf]; born Wijthoff; 6 October 1865 – 21 May 1939) was a Dutch mathematician.

Biography

[edit]

Wythoff was born in Amsterdam to Anna C. F. Kerkhoven and Abraham Willem Wijthoff,[1] who worked in a sugar refinery.[2] He studied at the University of Amsterdam, and earned his Ph.D. in 1898 under the supervision of Diederik Korteweg.[3]

Contributions

[edit]

Wythoff is known in combinatorial game theory and number theory for his study of Wythoff's game, whose solution involves the Fibonacci numbers.[2] The Wythoff array, a two-dimensional array of numbers related to this game and to the Fibonacci sequence, is also named after him.[4][5]

In geometry, Wythoff is known for the Wythoff construction of uniform tilings and uniform polyhedra and for the Wythoff symbol used as a notation for these geometric objects.

Personal life

[edit]

Willem Abraham Wythoff was the youngest of four children born into the wealthy family of Abraham Willem Wijthoff and Anna Catharina Frederika Kerkhoven. His father was a Lutheran and son of the Amsterdam sugar refinery family Wijthoff & Son. His older sisters were: mathematician Geertruida "Truida" Wijthoff, writer Henriëtte Wijthoff and illustrator Anna Catharina Frederika Wijthoff.[6]
