Julio Kilenyi was born in Hungary in the city of Arad, later part of Romania. He studied in Budapest, Germany, and France before he immigrated in 1907 to Argentina and in 1916 to the United States, becoming a US citizen in 1924. Kilenyi designed the Olympic commemorative medal and the official Olympic poster for the 1932 Los Angeles Games, and predominantly produced plaques and medals, especially for prominent pioneers of his time. Four thousand copies of the Olympic commemorative medal were produced by the Whitehead-Hoag company in Newark. It weighed 147 gm, with a diameter of 69 mm and a thickness of 6 mm. The obverse was also used for the medals for the competitors in the demonstration sports.
