This result earned him the Szegő Prize in 2008 and a permanent, revered spot in the history of harmonic analysis. Any Bela Fejer obituary would be incomplete without the testimony of his students. At the University of Illinois at Chicago (UIC), where he held a joint appointment from 1998 until his retirement in 2022, Bela was famous for his “Socratic slaughter”—a teaching method where he would respond to a student’s hand-raised question not with an answer, but with a Socratic question of his own, often leading the student to discover the error themselves.

BUDAPEST, Hungary & CHICAGO, USA – The global mathematics community is mourning the loss of Professor Bela Fejer, who passed away peacefully on October 12, 2024, at the age of 69, surrounded by his family in Budapest. While an official Bela Fejer obituary has been circulated by the Alfréd Rényi Institute of Mathematics, the depth of his influence—spanning approximation theory, Fourier analysis, and the nurturing of young minds—requires a far more extensive recollection. bela fejer obituary

But to reduce Bela Fejer to dates and survivors would be to miss the point entirely. To his students, he was “The Equalizer.” To his peers, he was the man who solved the Fejer Conundrum —a problem his own grandfather, the legendary Lipót Fejér, had posed in 1918 and left unsolved for nearly a century. Born in Budapest in 1955, Bela Fejer grew up under the long shadow of his grandfather, Lipót Fejér—one of the founding fathers of modern harmonic analysis. For any young mathematician, such a lineage is both a blessing and a curse. In his early twenties, Bela struggled to emerge from the academic orbit of his forebear. He often joked, “At family dinners, they didn’t ask if I liked math. They asked if I had found a new proof for Fejér’s theorem yet. I was ten.” This result earned him the Szegő Prize in
