By a secret agreement, the existing 37 stockholders conveyed their shares "in trust" to nine trustees:[15] John and William Rockefeller, Oliver H. Payne, Charles Pratt, Henry Flagler, John D. Archbold, William G. Warden, Jabez Bostwick, and Benjamin Brewster.[16] This organization proved so successful that other giant enterprises adopted this "trust" form.
