Florence Harding, American publisher, 31st First Lady of the United States (d. 1924)
Florence Mabel Harding (née Kling; August 15, 1860 – November 21, 1924) was the first lady of the United States from 1921 to 1923 as the wife of President Warren G. Harding.

Florence first married Pete De Wolfe and had a son, Marshall. After divorcing him, she married the somewhat-younger Harding when he was a newspaper publisher in Ohio, and she was acknowledged as the brains behind the business. Known as The Duchess, she adapted well to the White House, where she gave notably elegant parties.
