After majoring in electrical engineering from Alabama Polytechnic Institute, Ed Argo joined the National Guard and was called up to serve in the US Army Field Artillery during World War One. Like many US equestrians of his era, he trained at the US Cavalry School at Fort Riley, Kansas and despite a lack of experience was picked for the American team for the 1928 Games. The last man to be added to the roster, he was only to be a reserve in Amsterdam. At the 1932 Olympics, Capt. Ed Argo won the jumping discipline and placed second in the dressage phase but fared badly in the cross-country event after falling at the water jump and dislocating his shoulder. He finished eighth in the overall individual placings. Argo was a West Point graduate, class of ‘18, who served as a lieutenant during the First World War. He was a career officer, retiring in 1944 as a colonel. After leaving the army he taught military science and tactics at Louisiana State University.
