Ronald L. Magolda, 54, of Wallingford, a pharmaceutical company vice president, died Sunday at the Hospital of the University of Pennsylvania of injuries from a fall that day while he and his wife rode bicycles on the Swarthmore College campus.

Dr. Magolda graduated from Vineland (N.J.) High School and earned a bachelor's degree in chemistry from Villanova University, where he met his future wife, Diane Schneider.

In 1988, he received the Villanova University College of Arts and Sciences Alumni Medallion for achievement in his field.
