He was Glenn Gould’s piano tuner. The New York Times has an obituary. Better: from the Glenn Gould Foundation, an appreciation by the writer Katie Hafner. An excerpt:
Over the years Verne collected dozens of tools. Some he bought from old-timers, and others he adapted from other trades. He had surgical forceps and dental explorers, which made dandy hooks, opticians’ screwdrivers for adjusting harpsichords, barber scissors for trimming felt, and shoemaker pegs for plugging holes. From the welding trade he took soapstone, a dry lubricant for the buckskin that can squeak in the action of older pianos.There’s a filmed interview too.
