The late Frank Zamboni patented a number of inventions but is remembered for the one that bears his last name: the Zamboni, a large, mobile machine that resurfaces the ice in ice rinks.
The Utah native, son of Italian parents, came to inventing by way of first owning an electrical supply business serving the dairy industry and later a plant that made block ice. The patent for his Zamboni was submitted in 1949 and granted in 1953.
These big, effective machines are still in use today. Zamboni died of cancer in 1988.
