“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—exterior the odd.”
Three of Blum’s college students have additionally gained Turing Awards; many have acquired different excessive honors in theoretical pc science, such because the Gödel Prize and the Knuth Prize; and greater than 20 maintain professorships at prime 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 good 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 needed to work with him. “Manuel was heat, smiling, and simply instantly emanated kindness,” Harchol-Balter instructed me. Her specialty, queueing principle, had little overlap with Blum’s, however he took her on. “Each professor I do know, should you begin engaged on what’s approach out of their space, they’d inform you to go discover someone else,” she stated. “Not Manuel.”
Just a few months in the past, as I used to be studying about among the most important but counterintuitive concepts in fashionable theoretical pc science, I spotted that the overwhelming majority of the researchers chargeable for that work had been suggested by Blum. I puzzled whether or not there is likely to be some system to his success. After all, it’s presumptuous to assume such an intimately human course of will be distilled into an algorithm. Nevertheless, conversations along with his college students gave me a way of his strategy and revealed constant themes. Many spoke warmly of him: I typically heard some model of “I might speak about Manuel all day” or “Manuel is my favourite matter of dialog.” The finer factors of mentorship apart, what I realized was a minimum of proof that kindness can beget greatness.
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 girls’s school 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 break 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 steadily erupts right into a resonant snicker; he’s charismatic in a approach typical of people who find themselves completely oblivious to their charisma. (When he says “WON-derful,” which he steadily does, you possibly can virtually hear “WON” in all caps.)
The Blums, who not too long ago celebrated their 62nd anniversary, nonetheless shuttlecock analysis concepts, enthuse over emails from their former college students, and full one another’s reminiscences—some relationship from their life in Venezuela, the place they met as youngsters.
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 after they moved to the Bronx, his household realized that folks 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 be taught English for college, he quickly forgot Spanish as effectively.
