In 2026, Vaisala celebrates its 90th anniversary and nine decades of turning curious ideas into bold measurements and real-world impact.
Our history begins in 1936, when Professor Vilho Väisälä invented his first radiosonde and sold it to MIT. That moment sparked a legacy of world-leading measurement and a startup spirit that still drives us today.
Since then, innovation has been at the core of Vaisala. Raised by curiosity and driven by purpose, we build breakthrough measurement technologies that shape industries and save lives. We think like a startup, act like a pioneer, and deliver like a global leader.
Over the decades, our innovations have set new standards, from Humicap, the first thin film capacitive humidity sensor, to automated aviation weather systems. Our instruments help explore Mars, protect critical transformers, and optimize wind energy with LiDAR. We safeguard conditions for the world’s largest pharmaceutical companies and power Xweather services that provide real-time, hyperlocal weather intelligence.
Our 90th anniversary celebrates everyone who has contributed to Vaisala’s journey—from the visionaries who laid the foundation to everyone shaping the company today. With a pioneering mindset, unwavering commitment, and a spirit of curiosity, we will continue to shape a safer, smarter, and more sustainable world for the next 90 years and beyond.
Thank you for building our future, since 1936 and now.
