Christoforidis did most of his early fighting in Europe, mostly in France. From 1934 until he came to the United States in late 1939, he had 46 fights in Europe. His first bout was against Theodore Korenyi in Athens, Greece, which he won by second round knockout. He made his United States debut on 5 January 1940 in Madison Square Garden, defeating Willie Pavlovich by decision. At that point, Christoforidis settled in Geneva, Ohio. On 8 November 1937, Christoforidis won both the Greek Middleweight and Greek Light Heavyweight titles from Costas Vassis in Athens, Greece. Christofordis defeated EBU (European) Middleweight Champion Bep van Klaveren on 14 November 1938 in Rotterdam, Netherlands and won the EBU title. One of the spectators was Adolf Hitler. Christoforidis ran a bar-restaurant in Geneva, Ohio, for a good number of years after he retired in 1947, and he enjoyed the Cleveland area. In 1961, Christoforidis and his wife got divorced and in 1968 he sold his interests in Geneva and moved to Florida to retire. In 1971, he took an extended trip back to Greece for the first time for a scheduled 45 days. However, he liked it so much, the 45 days turned into 15 years. Christoforidis was a hero in Greece and enjoyed the company of the rich and famous on the golf courses and, as he said, "being in shirt sleeves 12 months a year." Christoforidis died suddenly of an apparent heart attack October 31, 1985 in Athens, Greece at the age of 67. He has made history by becoming the first Greek professional boxing world champion.
