Perhaps I should say “facts” since I got them from his Wikipedia page (corroborated by more official accounts):

• “He was prevented from enrolling in university in 1939 due to the anti-Jewish laws then in force, but enrolled at the University of Budapest in 1940 and finished his studies in 1944. At this point he was drafted to forced labour service, escaped, and completed his Ph.D. in 1947 at the University of Szeged, under the advisement of Frigyes Riesz.” Hardcore!
• Rényi said “A mathematician is a device for turning coffee into theorems,” not Erdös.
• He passed away at the age of 48!
