Cornelius Vanderbilt
Commodore: The Life of Cornelius Vanderbilt, Edward Renehan
Note: although a post was written about this book, an alternate biographer of Vanderbilt claims that much of the ideas put forward in this book are false. An Amazon review explains in detail:

Stiles compellingly demonstrates that two diaries Renehan claimed to use to support his most sensational claim, that the Commodore suffered from syphilitic dementia for the last decade of his life and was no more than a puppet run by his son William, are imaginary. Renehan’s tale is contradicted by everything we know about syphilis; he refuses to let anyone examine his copies of the “diaries;” he refuses to name the present owners of the diaries; and, oh yes, he is currently doing time in New York for having stolen and sold letters by Washington, Lincoln, and Theodore Roosevelt belonging to the Theodore Roosevelt Association, of which he had been acting director.
