John Warne Gates, also known as "Bet-a-Million" Gates, was an American Gilded Age industrialist and gambler. He was a pioneer promoter of barbed wire. He was born and raised in what is now West Chicago, Illinois. He did not enjoy farm life and began offering neighbors various business propositions at an early age, including the sale of firewood to homes and to the local railroad. When he started a local grain brokerage that failed, Gates began spending time at the local railroad station and became reacquainted with the men he previously sold firewood to. He was invited to join their poker games and through this, Gates' aptitude for cards and other games of chance was developed.
