He was married once, to Erzsébet (Éva) Fejér, a linguist and translator. Theirs was a partnership of parallel solitude: she translated French poetry while he sketched inequalities. Éva predeceased him in 2015. They had no children. When asked why, Fejér reportedly replied, "I have thousands of children. They are called polynomials, and they behave better than humans."

Béla Fejér has written his last inequality. But the space he leaves behind—the space of functions, limits, and beauty—will continue to be explored for generations. He proved that precision need not be cold, that symmetry is a form of truth, and that a single, well-crafted theorem lasts longer than stone. He was married once, to Erzsébet (Éva) Fejér,
His family requested that donations in his memory be made to the St. Michael’s Hospital I.C.U. Fund , honoring the care he received during his illness. Queen’s Counsel designation or perhaps more details regarding memorial services in Toronto? They had no children
Diagnosed with idiopathic pulmonary fibrosis in 2019, Bela Fejer continued to work from his home in Budapest, collaborating with young researchers via an aging laptop that he famously refused to upgrade. “New computers make you lazy,” he told the Notices of the AMS in a 2022 interview. “I want my proofs to survive a power outage.”
Colleagues recall that Fejér could look at a sequence of polynomials and, almost by instinct, identify the precise inequality that governed their growth. "He saw through the notation," said Dr. Anna Kovács, a former student now at the University of Vienna. "Most of us compute. Béla listened to what the function was trying to say."
