Wilhelm Gross (24 March 1886, Molln – 22 October 1918, Vienna) was an Austrian mathematician, known for the Gross star theorem.
[1][2] Wilhelm Gross graduated from the Gymnasium in Linz and then studied from 1905 to 1910 at the University of Vienna, where he received his Ph.D. (Promotion) on 20 May 1910 with Wilhelm Wirtinger as thesis advisor.
In October 1910 Gross passed his teaching qualification examination in mathematics and physics.
After a three-semester stay in Göttingen during the years 1910–1912, he became in 1912 an assistant and from 1913 a Privatdozent at the University of Vienna.
In the same year he was awarded the Richard Lieben Prize for his research on the calculus of variations, but he died of influenza in the 1918-1920 pandemic.
