John R. Abernathy ("Catch 'Em Alive Jack")

John R. Abernathy, aka: Wolf Catcher, Catch 'Em Alive Jack (1876–1941) - Born to Scottish ancestors in Texas, Abernathy was raised in the burgeoning railroad town of Sweetwater. During his lifetime he worked as a U.S. Secret Service agent, a wildcat oil driller, and was the last U.S. Deputy Marshal in Oklahoma Territory, serving from 1906 to 1910. But he was best known for capturing hundreds of wolves single handedly without ever having to kill one. By forcing his hand deep enough into a wolf's mouth, he could stun the creature long enough to capture it, a service for which he was paid fifty dollars by eager ranchers. Earning him his nicknames and a small amount of fame for this "skill," he even drew the attention of President Theodore Roosevelt.
