“I don’t know what his secret has been. However he has been a tremendously profitable advisor,” says Michael Sipser, a theoretical pc scientist at MIT who was suggested by Blum, referring to the “extraordinary variety of PhD college students” who’ve labored with him after which gone on to make an influence within the discipline. “It’s extraordinary within the literal sense of that phrase—outdoors the peculiar.”
Three of Blum’s college students have additionally received Turing Awards; many have obtained different excessive honors in theoretical pc science, such because the Gödel Prize and the Knuth Prize; and greater than 20 maintain professorships at high pc science departments. There are 5, for instance, at MIT and three at Carnegie Mellon College (the place there have been 4 till one left to discovered Duolingo).
Blum can also be distinguished by the nice plurality of subfields that his college students work in. When Mor Harchol-Balter, a professor of pc science at Carnegie Mellon, arrived on the College of California, Berkeley, as a PhD pupil, she rapidly realized that she wished to work with him. “Manuel was heat, smiling, and simply instantly emanated kindness,” Harchol-Balter advised me. Her specialty, queueing idea, had little overlap with Blum’s, however he took her on. “Each professor I do know, for those who begin engaged on what’s approach out of their space, they might inform you to go discover anyone else,” she mentioned. “Not Manuel.”
A number of months in the past, as I used to be studying about among the most important but counterintuitive concepts in trendy theoretical pc science, I noticed that the overwhelming majority of the researchers answerable for that work had been suggested by Blum. I puzzled whether or not there could be some formulation to his success. In fact, it’s presumptuous to assume such an intimately human course of might be distilled into an algorithm. Nevertheless, conversations together with his college students gave me a way of his method and revealed constant themes. Many spoke warmly of him: I usually heard some model of “I may speak about Manuel all day” or “Manuel is my favourite subject of dialog.” The finer factors of mentorship apart, what I realized was not less than proof that kindness can beget greatness.
Sluggish starting
Manuel Blum is married to Lenore Blum, an achieved mathematician and pc scientist, who has additionally been on the forefront of selling range in math and computing (amongst different issues, she based America’s first pc science division at a ladies’s faculty and helped CMU’s pc science division obtain 50-50 gender parity). They’re each now emeritus professors at CMU and Manuel Blum is an emeritus professor at UC Berkeley; they cut up their time between the 2 coasts.
At some point in August, I joined the couple for breakfast at their home in Pittsburgh. Breezy in his method, Blum, at 85, nonetheless has a schoolboy’s smile and ceaselessly erupts right into a resonant chortle; he’s charismatic in a approach typical of people who find themselves totally oblivious to their charisma. (When he says “WON-derful,” which he ceaselessly does, you may virtually hear “WON” in all caps.)
The Blums, who just lately celebrated their 62nd anniversary, nonetheless shuttlecock analysis concepts, enthuse over emails from their former college students, and full one another’s reminiscences—some courting from their life in Venezuela, the place they met as children.
Manuel Blum was born in 1938 in Caracas to Jewish dad and mom who had moved from Romania. His first language was German, which his dad and mom spoke at dwelling. However once they moved to the Bronx, his household realized that individuals didn’t need to hear German spoken. The yr was 1942, and the nation was at struggle. After switching to Spanish at dwelling, he rapidly misplaced his fluency in German. However when he needed to study English for varsity, he quickly forgot Spanish as effectively.
