But the team showed spirit in a competitive 7âÂÂ0 loss at Michigan, then closed out the year with two straight wins for a final record of 6âÂÂ3âÂÂ1.
Prior to his time at Notre Dame, Diebold played cover point for the 1899âÂÂ1900 Pittsburgh Athletic Club ice hockey team that won the championship of the Western Pennsylvania Hockey League.
After graduation, Diebold returned to his hometown of Pittsburgh where he married Edna Louise Lally and worked in the family lumber business. At the time of his death, he was vice president of the Diebold Investment Company.
