Columbus, Ind.-based Cummins Inc. announced that Chief Technical Officer John Wall will retire in October after nearly 30 years with the company. Vice President of Engineering for Cummins’ Engine Business Jennifer Rumsey will succeed Wall.

“We are, of course, happy for John and excited about what the future might hold for someone with his energy and passion,” said Chairman and CEO Tom Linebarger and Rich Freeland, president and COO. “It’s a bittersweet moment, however, because John has played such an important role, not just in our company, but in emissions science and policy around the world.”

Wall joined Cummins in 1986 and became the top technical leader in 2000. He will retire October 31.

“We are fortunate to have someone with Jennifer’s expertise to take his place,” they added. “She has successfully worked across business units and regional boundaries and we have no doubt that Jennifer will continue John’s legacy of innovation and superior results.”

Rumsey, a Columbus native, started working at Cummins in 2000. She holds degrees from Purdue University and the Massachusetts Institute of Technology.

“I am honored for the opportunity to continue John Wall’s legacy of innovation leadership at Cummins. I look forward to building on his successes and taking Cummins’ technical organization to the next level by focusing on customer-driven innovation, global integration and our brand promise of dependability,” Rumsey said.
