A strict upbringing and his first bookkeeping job.
Entering the oil refining business in Cleveland.
Building Standard Oil.
Public anger and the breakup.
Philanthropy and later life.

A closer look

Chernow paints Rockefeller as a man of contradictions. He was deeply religious, careful with every cent and personally modest, yet he built one of the most feared monopolies in history using secret rebates from railroads and pressure on competitors.

The later chapters cover his philanthropy, which funded the University of Chicago, medical research and public health work. Chernow shows how Rockefeller approached giving with the same system and patience he brought to business.

Tips from readers, plus one of ours

Budget the time. Business Nous's review puts it at well over 700 pages and says the middle third, full of railroad rebates and lawsuits, is where readers stall.
Push through to the end. The same review says readers who finish often rate the final part, on his philanthropy and long retirement, as the best.
Read it for the paradoxes. the Kirkus review notes how Chernow used a 1,700-page interview Rockefeller gave in retirement and shows a man who tried to end wasteful competition and ended up with his company broken up.
Look for the solder story. Reviewers point to the scene where Rockefeller cut a drop of solder from each kerosene can as the clearest picture of how he thought about costs.
Agree or disagree: some readers say it's a book about oil. We disagree. The oil is the setting, and the story is about character, discipline and how he chose the part of the industry with the most leverage.
Our unusual tip: as you read, keep your own Ledger A, the account book Rockefeller kept from his first job, for one week. Write down every purchase and every gift. It's the fastest way to feel the habit Chernow says shaped everything he did.
