She was only two feet, eight inches tall, but more than a century later, her legend reaches out to us. As a child, Mercy Lavinia “Vinnie” Warren Bump was encouraged to live a life hidden away from the public. Instead, she reached out to the immortal impresario P. T. Barnum, married the tiny superstar General Tom Thumb in the wedding of the century, and became the world’s most unexpected celebrity. Vinnie’s wedding captivated the nation, preempted coverage of the Civil War, and even ushered her into the White House. But her fame also endangered the person she prized most: her similarly sized sister, Minnie, a gentle soul unable to escape the glare of Vinnie’s spotlight.
