Charles Babbage hated organ grinders. Calling them the worst of the “thousand nuisances” that made it “impossible for the householder to enjoy any quiet,” he claimed that such “instruments of torture” had cost him a quarter of his working life. At one point he tallied 165 “nuisances” in 90 days.

“It is difficult to estimate the misery inflicted upon thousands of persons,” he wrote, “and the absolute pecuniary penalty imposed upon multitudes of intellectual workers by the loss of their time, destroyed by organ-grinders and other similar nuisances.”

He spent £170 on a soundproof room in his Cheyne Row house to protect him from “vile yellow Italians”; it didn’t work. When a magistrate asked if he really believed that listening to a hand organ could impair a man’s brain, he replied, “Certainly not, for the obvious reason that no man having a brain ever listened to street musicians.”

Sadly, he was as much renowned for this crusade as for his scientific accomplishments — his 1871 obituary in the London Times notes that he lived to be almost 80 “in spite of organ-grinding persecutions.”
