Von Porat was born in the little parish of Pjätteryd, Kronoberg County, Sweden, into an independently wealthy family. The von Porats lived on a huge estate in Sweden. An English tutor gave von Porat and his three brothers their early education, hence von Porat learned to speak English with a decidedly British accent. He also learned to speak Danish, Swedish, Norwegian, German and French fluently. While very young, he and his family moved to Copenhagen, Denmark, where his father organized a branch of the Berlitz Language School. In early 1914 the family settled in Oslo, Norway, where his father made extensive maritime investments. The von Porat fortune disappeared rapidly when World War I came along, forcing the four von Porat boys to seek work.
Amateur career
It was while employed as a minor clerk in the office of an Osloshipping agent that von Porat became interested in boxing. He knocked out two opponents in one evening during his first amateur tournament. Shortly thereafter he knocked out the amateur middleweight champion of Denmark in two rounds. Otto von Porat went on to flatten all the bestheavyweight amateurs in Europe, then won the Olympic Heavyweight Gold Medal at the 1924 Paris Olympics. He returned to Norway to serve in the Norwegian Army. He represented the club Oslo AK.
Pro career
Von Porat then came to the United Statesin the Summer of 1926, turning professional at that time. He generally fought in the rings of Minneapolis, New York City, and Chicago. He was a huge drawing card in the Chicago area. He could often be found at the Chicago Norske Klub, a Norwegian-American cultural center. It is said that his fight with Paulino Uzcudun "gave rise to the wide-spread impression that von Porat lack aggressiveness and... the 'killer instinct.' Although he had a once-promising career and was a top contender for the Heavyweight Title, von Porat apparently lacked self-confidence and thus "lost fighting strength in the rough American school."
Life after boxing
After his boxing career ended von Porat continued to live in Chicago. In 1982 he died in Bærum, Norway.
