Arthur Julius Marx was an American author, a former ranked amateur tennis player, and son of entertainer Groucho Marx and his first wife, Ruth Johnson. Marx spent his early years accompanying his father around vaudeville circuits in the United States and abroad. When he was 10, the family moved to Southern California, where the Marx Brothers continued their film careers. Marx was a nationally ranked tennis player before he was 18. While he was attending the University of Southern California, he won the National Freshman Intercollegiate Tennis title at Montclair, New Jersey. At the Cincinnati Masters, Marx reached the singles final in 1941 before falling to Bobby Riggs. To reach the final, Marx knocked off future International Tennis Hall of Fame enshrinee John Doeg in the round of 16, Frank Froehling in the quarterfinals, and Gardner Larned in the semifinals
