Before Dynamatic® was known for Eddy Current Technology, there was the Winther Motor & Truck Company.

Founded by Martin & Anthony Winther in 1916, the company built vehicles and developed a reputation for innovative engineering.

That early spirit of innovation eventually led to the founding of Dynamatic in 1931.

95 years later, we're still moving forward with that same mindset.
