Question 2

This doctor has a middle initial of "H", a wife named Mary, and the first story this man appears in is subtitled as being told from his perspective. That same first story establishes that this man earned his medical degree from the University of London in 1878 before serving in the army where he was wounded at the Battle of Maiwand in the Second Anglo-Afghan War.

Dr. John H. Watson (flatmate and partner of Sherlock Holmes)
