Henry Milner Rideout Sr. is my grandfather. He was a 1899 graduate of Harvard. He was an instructor for a short period (1900-1904)before he became a writer. The Archives at Harvard have some but very limited information on him. The Library has 18 of the books he wrote. He died September 17,1927 at age 50 of polio. He married Francis Cecilia Reed in 1909. They had three children Clara Avery, Henry Milner Jr., my Dad and Cecily Reed. I have been searching for his boks with only limited success.
