Alberto Calderon, considered one of the century's most influential mathematicians, died Thursday at Northwestern Memorial Hospital after a short illness, the University of Chicago said.

Calderon, 77, was university professor emeritus of mathematics at the University of Chicago. He was best known for his contributions to mathematical analysis, the large branch of mathematics that includes calculus, infinite series and the analysis of functions, the university said in a statement.Together with his mentor, Antoni Zygmund, he founded the influential Chicago school of analysis, it said.

Calderon won the 1991 National Medal of Science, the 1989 Wolf Prize, the 1989 Steele Prize from the American Mathematical Society and the 1979 Bocher Memorial Prize from the American Mathematical Society.
