A closer look
Cannadine shows Mellon learning from his father, Thomas, who taught him to judge people and projects carefully. Andrew became known for listening and saying little.
The Alcoa story shows his style. When inventors came looking for money to make aluminum cheaply, Mellon saw the promise and took a stake. He stayed involved as the company grew.
His time at the Treasury covered the boom of the 1920s and the start of the Depression. Cannadine is balanced on his tax cuts and the criticism he faced as the economy collapsed.
The National Gallery was his final big project. He gave his collection and funds for the building, shaping American art life.
