In 1931, Professor Vilho Väisälä found a fallen Russian radiosonde. He admired its idea to use radio technology to retrieve observation results but, an innovator at heart, wanted to improve it to his quality standards. Väisälä finalized his famous innovation in 1936, founded Vaisala, and sold the first radiosonde pieces to MIT, Massachusetts Institute of Technology. A new global technology pioneer was born. Today, Vaisala is a global leader in weather, environmental, and industrial measurements headquartered in Vantaa, Finland. Building on over 80 years of experience, Vaisala strives towards its mission of Observations for a better world.
