Dr. Harold Greenspan is the name of a world-renowned chief of service in the department of medicine and author of a textbook on cardiology. He got caught in controversy by unknowingly defending a subordinate's faulty research. Konner dismissed this oversight as a typical problem with overburdened scientists. Greenspan emphasized it was impossible to memorize two thousand pages of medical data. He claimed students could more effectively conquer the data by reading and understanding pertinent information patient by patient.
