Horatio attended University School in Cleveland and graduated from Sheffield Scientific School at Yale University in 1903. In 1909, he took a course in agriculture at the Ohio State University.
After graduation from college, he spent a year as Secretary to the American Commission to Abyssinia (Ethiopia) and was decorated with the Order of the Star of Ethiopia. The next four years were spent in the oil fields and on a cattle ranch in Oklahoma. He returned to Spring Hill and was connected with the First National Bank 1915-1917, and with the C.W. Stuart Co., 1920-1923.
In 1909 he began remodeling the house, as there was no central heating, electricity, or plumbing, and in October 1910, married Irene McLain.
He was a veteran of World War I, entering the second officer’s training camp at Fort Benjamin Harrison, Indiana, in 1917 and became a first lieutenant of field artillery. He served overseas in 1918 with the Headquarters company of the 322nd Field Artillery, 158th Brigade, 83rd Division.
Soon after returning to civilian life in 1919, he joined with a group of other veterans in founding Massillon Post No. 221, American Legion, where he was a charter member and served as the second commander.
He managed the farm and was a true country gentleman and sportsman. The family and their friends all remember the hospitality of the home and the delicious and unusual meals served there.
Mr. and Mrs. Wales both had riding horses and were active in area hunts, and Horatio traveled throughout the country on fishing and hunting trips.
