On September 26, 1855, sixteen-year-old Rockefeller got his first job as an assistant bookkeeper at Hewitt & Tuttle, a Cleveland produce commission firm. He was not told his pay for three months, then received about $50, and he kept every receipt and expense in a small notebook he called Ledger A. Decades later he still celebrated the anniversary of that hiring and treasured the ledger, treating exact bookkeeping as the origin of everything he built.
Rockefeller argues that the oil refiners of the 1860s–70s were destroying each other through overcapacity and price wars. He says consolidating them into Standard Oil was a rational act of cooperation that gave them efficiency, scale, stable supply, and export markets.
Rockefeller treats philanthropy as a discipline that needs the same investigation, organization, and efficiency as business. He holds that careless alms create dependency. Money should instead go to permanent institutions that attack root causes and help people help themselves, run by expert boards instead of by the donor's personal impulses.
He barely touches episodes like the South Improvement Company and redescribes contested tactics as ordinary business practice. The evidence therefore sits in what the author skips or reframes, so a self-authored account is most useful when set against the record it avoids.
