Who organized the standard oil trust in 1879?

oil companies has been around for at least one hundred years before John Rockefeller established the Standard Oil Trust Company. Just like any new business founded, Rockefeller thought it was a new investement with the steel company becoming one of the dominant industry in the world, due to railroads, train, and new ships being created. They required oil to function. John Rockefeller, established the Trust, a type of monopoly (illegal today in the US) with the idea to make more money. Much more than what he realized.
