A guide to Wisconsin’s technology and entrepreneurial milestones.
Wisconsin has a rich history of innovation and entrepreneurial activity. From its territorial days to the first decade of the 21st century, the state has produced ideas, inventions and intellectual property that have improved life for millions of people in Wisconsin and around the world.
Understanding Wisconsin’s entrepreneurial past is critical to envisioning its exciting future as a place to work, live and grow a business. We have built a foundation of innovation over the years, and we continue to welcome people, ideas and companies that will strengthen that base as we reach new heights as a state and a region.
As you read this timeline, you will come across many familiar names from the fields of science, agriculture and manufacturing — from Babcock to Temin, from Kohler to Thomson, and from Evinrude to DeLuca. These pioneers help tell the story of Wisconsin through their enduring legacies.
Wisconsin’s combination of educational, research and business resources have made this a state where innovation is a way of life. Please read on to learn more.
