Legacy
Leads Cummins through the dual mandate of improving the core power business while funding Accelera and lower-emission technologies. Rumsey, Cummins' seventh CEO and the first woman to lead the company since its 1919 founding, joined in 2000 and rose through engineering leadership roles including chief technical officer overseeing roughly 11,000 employees and president of the Components segment before becoming CEO on August 1, 2022. She holds mechanical engineering degrees from Purdue University and MIT. She has directed Cummins' strategy of pursuing multiple powertrain paths simultaneously -- diesel, natural gas, hydrogen, and battery-electric -- through the company's Accelera business unit, betting that heavy-duty trucking will require a mix of technologies rather than a single electrification path given the industry's demanding duty cycles and refueling infrastructure constraints. She has continued Cummins' longstanding presence in Columbus, Indiana, maintaining the company's deep community ties in its headquarters town even as Cummins has grown into a global manufacturer with operations across dozens of countries. Before joining Cummins in 2000, she worked on control systems at a fuel-cell startup in Cambridge, Massachusetts.
