Welcome to the inaugural edition of Monday Morning Math! Every Monday Morning during the semester we’ll be posting some information about a mathematician, or some fun math. (For us it is, admittedly, a nice way to say Hello! to the blog again, which has not had many posts lately [*cough* understatement *cough*].

Our first mathematician is Alberto Pedro Calderón. He was born on September 14, 1920, in Mendoza, Argentina, and worked as an engineer before earning a PhD in mathematics. This early engineering seems to have stuck with him:

[His] revolutionary influence turned the 1950s trend toward abstract mathematics back to the study of mathematics for practical applications in physics, geometry, calculus, and many other branches of this field. His award-winning research in the area of integral operators is an example of his impact on contemporary mathematical analysis.

The prizes mentioned above include the Wolf Prize (“for achievements in the interest of mankind and friendly relations among peoples”) and the National Medal of Sciences (for “outstanding contributions to knowledge in the physical, biological, mathematical, or engineering sciences.”)

One of Calderón’s graduate students, Carlos E. Kenig, described him in the following way:

Alberto Calderón was a very unassuming man of natural charm, a person of great elegance and restraint, and wonderful company. Mathematically Calderón was exceptional not only for the strength of his talent but for his peculiar way of grasping mathematics. He redid whole theories by himself, got to the core of what he wanted to know by himself, found always his own way. His ideas and the methods he developed were always extremely original and powerful.

Alberto Pedro Calderón passed away on April 16, 1998, in Chicago, Illinois. A biography at the University of Chicago noted:

Calderón is survived by his wife, noted mathematician Alexandra Bellow (née Bagdasar), recently retired from Northwestern University, whom he married in 1989; and two children from his first marriage, Mary Josephine, of St. Charles, Ill., and Pablo, of New York, N.Y.His first wife, Mabel (née Molinelli Wells), to whom he was married for 35 years, died in 1985.

Don’t want to wait a whole other week before reading about another mathematician? The website Lathisms (Latinx and Hispanics in the Mathematical Sciences) is posting a biography every day during Hispanic Heritage Month (Sept 15-Oct 15)
