In 1903, John Rockefeller, credited to be America's first billionaire, and one of the richest people in modern history, founded the General Education Board (GEB).
He is also credited to have founded three universities- the University of Chicago, the Rockefeller Institute for Medical Research which has now become Rockefeller University and the Central Philippine University.
The General Education Board (GEB) was established to promote education at all levels everywhere in the country, through funding, supporting, and developing curriculum for schools in America, and by extension globally.
They significantly shaped what is known today as 'Modern Education System'.
