  ## The Colburn Family
  
  Herbert C. Colburn and Ernest A. Colburn Jr. were the sons of Judge Ernest A. Colburn (E.A. Colburn). Judge Ernest was wealthy, having made his fortune as a mine owner in the Cripple Creek, Colorado mining district. He was the financial backer of the automobile while the car itself was designed and built by his sons.
  
  Herbert and Ernest Jr. were inventors and had interests in engineering and technology, and held at least two patents for the design of mining machinery. At one time, the brothers ran the Ajax Mine in Victor, one of the many mines owned by their father.
