He competed in the 1936 Summer Olympics. As a Jew, he had some hesitation about playing in the Olympics hosted by Hitler's Germany, but was persuaded when he was assured by Avery Brundage that there would be no Nazi propaganda at the games. The Nazi regime had passed the anti-Semitic Nuremberg laws the prior Fall which stripped German Jews of citizenship, opportunities to receive a public education, and access to many professions and public facilities. Jewish businesses had been boycotted, forcing many businesses to close, and Jews could not serve in the legal profession, the civil service, teach in secondary schools or universities or vote or hold public office.[3][5]
At the 1936 Berlin Olympics, Balter was part of the American basketball team which won the gold medal. He played in two matches, but not the final match in which the U.S. team won the gold medal. He was one of a number of Jewish athletes who won medals at the 1936 Berlin Olympics during the Nazi regime.[6] The Berlin Olympic final concluded the first official Olympic Basketball competition, with the United States defeating Canada, 19–8. At the games, the medals were awarded by James Naismith, the inventor of basketball. The game was low scoring, as it was played outdoors in a converted tennis stadium with clay courts that had become somewhat muddy after a heavy rain, making dribbling and ball handling difficult. Irving Maretsky, a member of the Canadian team they played in the final game, noted that the American's height advantage was a key component in their victory, as at the time the rules required each score to be followed by a jump at center court. The wet court also made rapid passing and dribbling difficult, making height more of a factor than speed or ball handling.[7]
Balter later turned his celebrity into a career as a Los Angeles sportscaster, announcing at radio station KLAC from 1946 to 1962, and starting his TV career on a local station in 1950. He was known as the "voice of UCLA football and basketball" and also wrote sports columns for the Los Angeles Herald-Express.[8][9]
