PERSON
Richard Hamming
The mathematician who made unreliable hardware trustworthy—inventor of error-correcting codes, author of “You and Your Research,” and the clearest voice on the distinction between producing numbers and achieving insight that defines the deepest question of the AI era.
Richard Hamming spent his entire career inside computing and never once trusted the computer. He managed the calculating machines at Los Alamos that ground out the numbers for the atomic bomb, watched the physicists treat those outputs as oracles, and drew the lesson that stayed with him for life: a machine can be exquisitely productive and completely wrong, and the two look identical from outside. At Bell Labs in the late 1940s, exasperated by relay computers that halted at the first error and waited for a human who would not arrive until Monday, he asked the engineer’s question that changed the field: if the machine can detect an error, why can’t it locate and correct it? The answer became the
error-correcting codes that now quietly underwrite every phone call, hard drive, and deep-space transmission. He also chose, at the end of a career filled with technical achievement, to spend his teaching years at the Naval Postgraduate School insisting
