Ilya Piatetski-Shapiro

Ilya Piatetski-Shapiro (Hebrew: איליה פיאטצקי-שפירו; ; 30 March 1929 – 21 February 2009) was a Soviet-born Israeli mathematician. During a career that spanned 60 years he made major contributions to applied science as well as pure mathematics. In his last forty years his research focused on pure mathematics; in particular, analytic number theory, group representations and algebraic geometry. His main contribution and impact was in the area of automorphic forms and L-functions.

For the last 30 years of his life he suffered from Parkinson's disease. However, with the help of his wife Edith, he was able to continue to work and do mathematics at the highest level, even when he was barely able to walk and speak. Provided by Wikipedia
