Who invented the first practical and commercially successfully snowmobile?

The first practical and commercially successful snowmobile was invented by Joseph-Armand Bombardier, a Canadian engineer, in the late 1930s. He developed the B7 in 1942, which was designed to transport people and goods over snow-covered terrain. Bombardier's innovation laid the foundation for the snowmobile industry, leading to the production of numerous models that became popular in the following decades. His contributions significantly improved winter transportation and recreation.
