Dr. Robert E. Gilbert, professor of political science at Northeastern University, discusses how profoundly affected President Coolidge was by the death of his 16-year-old son, Calvin Jr., as a result of blood poisoning in 1924. This experience plunged him into a deep and devastating depression from which he never fully recovered. Calvin Coolidge, governor of Massachusetts and 30th president of the United States has often been described as a do-nothing, incompetent president who slept 15 of every 24 hours, despite having been a respected and capable governor.
