John Cheffers; BU professor studied sports fans’ behavior
An authority on crowd behavior, John Cheffers studied why sports fans wave giant foam fingers and sometimes angrily pelt players with cups. Dr. Cheffers also wrote extensively about the science of teaching physical education. At Boston University, where he led the Human Movement Program for more than 20 years, Dr. Cheffers was a mentor to scores of college students who marveled at the boomerang in his office and his tales of coaching in South Africa in the 1960s. He died Oct. 28.
