Local doctor in Harrow for 21 years. His British Medical Journal obituary can be found on the internet. It details that which it claims to have been: The most exciting incident in his career. Erzeroum was beleaguered by Russians, frost-bound, and infested with typhus, which had prostrated twenty-seven of the medical staff. To relieve the others volunteers were needed, and Stiven and another set forth from Trebizond for the purpose. In seven days they traversed 150 miles of almost trackless snow and ice; their guide deserted them, and their sole hope was to follow the tops of the telegraph poles which just protruded above the snow. Stiven did not stay long in Erzeroum; he returned to Constantinople, and was there attacked with typhus. For his services he was awarded the third class of the Osmanieh and Medjidieh orders and the Turkish war medal. The Harrow Gazette also carried a glowing obituary. Neither mentioned the event in his career, possibly seemingly minor at the time, and probably forgotten in 1902, which later events came to show might otherwise have been worth mentioning; that in the 1890s he'd operated on a teenager and saved his life. Of the incident, that teenager would later, in his biography, thank and credit his parents with and for affording the very best in medical and surgical treatment without which he would not have had the chance to flower. That teenager was Winston Spencer Churchill.
