If they use their focus, drive and determination, Cancers are capable of great things and John D Rockefeller, born today in 1839, is a great example of this.  He used his determination within the world of business and industry to revolutionize the petroleum industry. As kerosene and gasoline grew in importance to the world, the success of his business made Rockefeller America's first billionaire and even now he is often thought to have been the richest person in history.

Carrying on the family Cancer success story, John D Rockefeller's grandson, Nelson Rockefeller, was born sixty nine years to the day after his grandfather on 8 July 1908. Nelson used his Cancerdetermination in a different field to his grandfather. Although he started out working in various family-run businesses he went into politics, firstly as governor of New York and then as Vice-President to Gerald Ford from 1974 to 1977, although neither his family connections or Cancerdetermination could help him realise his desire to become President of the United States.
