Zoltan Nagy (d. September 14, 1917) claimed to be Gyula Nagy's son. In 1917, he traveled with his supposed father, acting as a "batboy" for the St. Louis Browns baseball team. In early September, second baseman Laszlo Kovacs got the impression that Zoltan was a vampire, a fact which he proved in Detroit when he caught sight of Zoltan's empty clothing in a mirror.
