# Cornellians at the International Congress of Mathematicians

The International Congress of Mathematicians (ICM) organized by the International Mathematical Union (IMU) meets every four years. It is the largest conference on mathematics. The Fields Medals, the Nevanlinna Prize, the Gauss Prize, and the Chern Medal are awarded during each congress. This page records the Cornell faculty and former Cornell Ph.D.s who have been invited to speak at the International Congress of Mathematicians. Plenary speakers address the entire congress and an invitation is one of the highest recognition a mathematician can receive from the community. Four plenary speakers were invited at the first Congress, hosted in Zurich in 1897, and about twenty plenary speakers are invited at recent Congresses.

The International Mathematical Congress that was held in Chicago in 1893 on the occasion of the Wold's Columbian Exposition is considered the precursor of the ICM as well as a key event in the development of in the United States.

In the picture, Felix Klein stand in the middle. Seating on the first row are James Oliver (Chair at Cornell) and William Story (Chair at Clark University). Henry Turner Eddy, the first Cornell Ph.D., is fifth from the left on the third row. Also on the third row, second from the right, is Cornell's professor James McMahon.

This page provides the complete list of those Cornell faculty and former Ph.D. students who spoke at the International Congress of Mathematicians at some point during their entire career. The dates of the Cornell appointment or the year of the Ph.D. are provided as well as the title of the address presented at the congress. The names of plenary speakers appear emphasized.Some Cornell undergraduates are also included with their graduation year but it is likely that not all of them are listed at this time.
