Ad Toepperwein was the greatest marksman and trick shot gunman of his time. He set 14 world records during the 36 years that he toured the nation for the Winchester Arms Co. His most-publicized feat was a marathon exhibition held at the San Antonio Exposition and Fair Grounds in December, 1907. Using a .22-caliber automatic rifle, he fired at 72,500 wooden blocks over a 10-day period. Each block measured 2 1/2 inches in diameter and was hand-thrown into the air. In 10 days of shooting, about eight hours a day, he missed only nine times. Toepperwein also taught his wife Elizabeth to shoot. Elizabeth was the first woman to qualify as a National Marksman with the military rifle. Winshcester promoted the Topperweins as the "World's Greatest Shooting Team". As they toured the nation together, they set 26 world shooting records. Toepperwein was inducted into the Texas Sports Hall of Fame in 1966.
