A distinguished University of Maryland professor died while riding his bike after he was hit by a car, Montgomery County Police said.

The 81-year-old Chevy Chase man, Ned Gaylin, was a child and family psychologist, author and professor emeritus at UMD's School of Public Health.

Police said he was riding a three-wheeled recumbent bike eastbound on the Capital Crescent Trail on Little Falls Parkway when he was struck by a car.

The accident happened around 11:30 a.m. Monday morning, when Gaylin was crossing the parkway in a marked crosswalk.

He was struck by a 2002 Mercedes E320. The driver of the Mercedes was not injured.

UMD named a scholarship after Gaylin in 2005.

Montgomery County Police continue to investigate the crash. Anyone with information is asked to contact the collision reconstruction unit at 240-773-6620.
