RIN TIN TIN

Corporal Lee Duncan rescued Rin Tin Tin when he was a puppy from a bombed out German kennel near the end of World War I in 1918 and took the dog home to California. When a producer spotted the dog jumping over 10 feet at a dog show, Rin Tin Tin went on to star in movies and radio adventures before he died in 1932.
