This year, Cummins celebrates 100 years in Power Generation. It all started with the incorporation of Onan Corporation in 1920 – a family owned business founded by David W. Onan. “The Onan story has so many parallels with Cummins. It started with one business idea and one visionary entrepreneur. What D. W. Onan started as a small business in Minnesota thrived for 100 years and became a global industry leader,” stated Alex Savelli, Executive Director of Cummins Power Generation.
