Socialite and aviation enthusiast, Princess Anne was born in England to the 4th Earl of Mexborough, and became a princess upon marrying Prince Ludwig of Löwenstein-Wertheim-Freudenberg in Germany in 1897. Her husband died during the Philippine-American War. Known for her charm, she also invented an automatic balancing bed to prevent seas sickness, and became enamored of flying, eventually participating in events under her maiden name of "Lady Anne Savile" and setting several records. She financed WWI flying ace, Capt. Leslie Hamilton's attempt to fly over the Atlantic Ocean from England to Canada, and accompanied him and Lt-Colonel Frederic Minchin in the attempt. They were never seen again; the trio make a fine TeamWatch team.
