Fred S. Kummer Jr., a Missouri S&T graduate who built his general-contracting business into the world’s largest design-build firm for health care and financial facilities, died April 30 in St. Louis. He was 92.

Kummer and his wife June donated $300 million to Missouri S&T last fall to establish the Kummer Institute for Student Success, Research and Economic Development. Their donation is the largest single gift ever to any public or private university in Missouri and one of the largest ever to any university.

“We have lost a true champion for S&T and for higher education,” said Missouri S&T Chancellor Mo Dehghani. “No individual was more supportive of this institution, and no individual more passionate about advancing this university’s mission, than Fred Kummer.

“Even before his transformative gift last October, Fred’s contributions to S&T over the years have touched the lives of thousands of students,” Dehghani said. “His support for our student design teams, academic programs and buildings, scholarships, and alumni initiatives have touched many lives. And now, through the Kummer Institute initiatives, Fred’s influence continues. We send our sincere condolences to June and the entire Kummer family.”
