Who is Henry Adams from The Nick Adams Stories and what is their importance?

Henry Adams is Nick's father. He is a medical doctor and is shown helping out Indians in need in "Indian Camp." In his childhood, Nick has a great admiration for his father and learns much from him. Later in his life, recalling his childhood, he is grateful that his father taught him how to hunt and fish, since those are two hobbies which he has retained his entire life. His father evidently met some kind of unfortunate, untimely end, but the exact nature is not described.
