Rin Tin Tin (September 1918 – August 10, 1932) was a male German Shepherd Dog rescued from a World War I battlefield by an American soldier, Lee Duncan, who nicknamed him "Rinty". Duncan trained Rin Tin Tin and obtained silent film work for the dog. Rin Tin Tin was an immediate box office success and went on to appear in 27 Hollywood films, gaining worldwide fame. In 1929, Rin Tin Tin may have received the most votes for the first Academy Award for Best Actor, but the Academy determined that a human should win. After Rin Tin Tin died in 1932, the name was given to several related German Shepherd Dogs featured in fictional stories on film, radio, and television. Rin Tin Tin, Jr. appeared in some serialized films. Rin Tin Tin III appeared in a film with child actor Robert Blake in 1947.
Duncan groomed Rin Tin Tin IV for the 1950s television series The Adventures of Rin Tin Tin, but the dog performed poorly in a screen test and was replaced in the TV show by trainer Frank Barnes's dogs, primarily one named Flame, Jr., called JR, with the public led to believe otherwise.
