Pat Reiffenstein

A graduate of the Ottawa Collegiate Institute (now the Lisgar Collegiate Institute) Pat Reiffenstein was a member of the Toronto Argonaut Rowing Club when he was selected to represent Canada at the 1904 Summer Olympics. There, alongside Alan Bailey, Phil Boyd, Thomas Loudon, Donald MacKenzie, Colonel Rice, George Strange, William Wadsworth, and Joe Wright, Sr., he lost to the Vesper Boat Club of the United States in the final of the coxed eights. As there were only two teams in the event, however, Canada earned a silver medal. Reiffenstein continued to row for the Argonauts after the Olympics and captured the coxless fours and eights titles at the 1905 edition of Canada’s Henley Royal Regatta. He was also a member of the Argonauts’ Rugby squad that won the season championship of the Ontario Rugby Football Union in 1901. Prior to World War I he worked as a bank manager and dog breeder in Napanee, Ontario and later fought overseas with the Royal Canadian Army during the conflict. Due to the anti-German sentiments that were prevalent following the war, he changed his surname to “Carr”, and later ran a farm in Dartford, Ontario, where he raised dairy cows and bred swine.
