Whether this was the result of his many and varied commitments or whether it was related to hubris (he was not a modest man) is not known. His personality has been analyzed by many, and it is not for us to speculate.1,9,11 In his years at the Johns Hopkins Hospital he had had difficulty with his fellow house officers, according to Finney.12 There are 2 letters in 1902 from Osler acting almost in loco parentis, gently suggesting to Cushing that he tone down his public criticism of others and his perceived arrogance.9 Dr Cheever observed, ”Cushing never put down deep roots in Boston, in spite of the favors and advantages, professional and social, which were so warmly heaped upon him.” Over the years he had an often contentious relationship with the Dean of the medical school, the hospital administration, and even with the President of Harvard University regarding a variety of issues. One in particular was over full time/part time practice of surgeons. His less than cordial relationship with Walter Dandy, MD, his colleague and rival neurosurgeon at Johns Hopkins, is well documented.1,9 Battles over budget, personnel, and space for beds and laboratory research, with acrimonious letters from Dr Cushing to the Dean and the hospital administration, are recorded as well as follow-up letters offering partial conciliation, if not contrition.13 At the 1946 meeting of the Harvey Cushing Society, Fulton noted, “The Chief was no plaster saint—he had an intense and at times a tempestuous nature which many of you know.”10
