I am John D. Rockefeller. In my latelife I focused on philanthropy and donated more than half a billion dollars to various educational, religious and scientific causes.
My charitable giving began with my first job as a clerk at age 16, when I gave six percent of my earnings to charity, as recorded in my personal ledger. By the time I was twenty, my charity exceeded ten percent of my income.
John D. Rockefeller have away $540 million( unadjusted for inflation) before his death in 1937 at the age of 97.
