Geoffrey Radbill, philanthropist, 78, dies after car driver hits his bike on Manhattan street

Geoffrey Radbill, a prominent Manhattan philanthropist whose generosity included large donations to his alma mater, was killed when a motorist slammed into the back of the bicycle he was riding along Riverside Drive, police said Friday.

Radbill, 78, who has a building at Bowling Green State University named after him, was pedaling near W. 158th Street Sunday morning when he was hit from behind by a Toyota sedan and was seriously injured, according to cops.

Radbill was rushed to Harlem Hospital, where he was pronounced dead.

The driver remained at the scene and was not charged with a crime. An investigation is underway, officials said.

Radbill, a longtime resident of the Upper West Side, was a successful financier and generous supporter of his alma mater, Bowling Green State University in Ohio, where in 2023 a renovated portion of the Mathematical Sciences Building was named in his honor.

The lights at the Geoffrey H. Radbill Center for College and Life Design were dimmed Sunday evening in tribute to the cycling philanthropist.

“Thanks to Geoff’s support and belief in the power of a Bowling Green experience, thousands of students have benefited from life-changing opportunities through Life Design,” university President Rodney Rogers wrote in a social media post.

“On a personal level, Geoff was a friend, and I will miss his advice, guidance and ideas. He was always ready to dream big.”

Radbill built his career at AXA-Equitable, a financial services company, where he was senior vice president and chief operating officer.

A Bowling Green biography says Radbill retired from AXA-Equitable in 2004 after 36 years with the company. His philanthropic work included the National Multiple Sclerosis Society and the Memorial Sloan-Kettering Cancer Center.
