Charles Fefferman

Fefferman contributed several innovations that revised the study of multidimensional complex analysis by finding fruitful generalisations of classical low-dimensional results. Fefferman's work on partial differential equations, Fourier analysis, in particular convergence, multipliers, divergence, singular integrals and Hardy spaces earned him a Fields Medal at the International Congress of Mathematicians at Helsinki in 1978. He was a Plenary Speaker of the ICM in 1974 in Vancouver.

At the age of 25, he returned to Princeton as a full professor, becoming the youngest person to be promoted to the title. He won the Alan T. Waterman Award in 1976 (the first person to get the award) and the Fields Medal in 1978 for his work in mathematical analysis, specifically convergence and divergence. He was elected to the National Academy of Sciences in 1979. He was appointed the Herbert Jones Professor at Princeton in 1984.

In addition to the above, his honors include the Salem Prize in 1971, the Bergman Prize in 1992, the Bôcher Memorial Prize in 2008, and the Wolf Prize in Mathematics for 2017, as well as election to the American Academy of Arts and Sciences and the American Philosophical Society. For 2021 he was awarded the BBVA Foundation Frontiers of Knowledge Award in Basic Sciences.
