Edmund Hlawka

Acclaimed Austrian mathematician Edmund Hlawka, a major influence in modern number theory, has died at age 92.
Hlawka's family says the renowned mathematician died on Feb. 19 in Vienna. A cause of death was not given, and it was unclear why the announcement came more than a week after his death.
Scholars have hailed Hlawka as one of the most important mathematicians of the 20th century. He was a leading number theorist who did groundbreaking work on the geometry of numbers and analytic number theory.
Hlawka was born on Nov. 5, 1916. He was a visiting professor at Princeton University and the Sorbonne in Paris, and did most of his work at Vienna's Technical University.
