Alberto P Calderón (September 14, 1920 - April 16, 1998) was a mathematician best known for his work on the theory of partial differential equations and singular integral operators .

He was born in Mendoza, Argentina, and graduated in civil engineering from the University of Buenos Aires in 1947 and gained a Ph.D. in mathematics from the University of Chicago in 1950.

In 1958 Calderón published one of his most important results, on uniqueness of solution of the Cauchy problem for partial differential equations. With his Ph.D. supervisor and mentor Antoni Zygmund he formulated the Calderón-Zygmund theory of singular integral operators .

During his career he held academic posts at Ohio State University, the Institute for Advanced Study, Princeton, the Massachusetts Institute of Technology and the University of Chicago, from which he retired in 1985. He was awarded many prizes for his work including the Bôcher Memorial Prize in 1975 and the Wolf Prize in 1989.
