In a This Day in History video, host Russ Mitchell takes us through the history of August 16th. On this day in 1829, Chang and Eng Bunker, a pair of conjoined twins from Siam, arrived in Boston to be put on exhibition. On this day in 1868, T.E. Lawrence, the British soldier who gained fame as Lawrence of Arabia, was born. On this day in 1988, George H.W. Bush picked Dan Quail to be his running mate on the Republican presidential ticket. Also, on this day in 1896, George Carmack struck gold while fishing near the Klondike River in Canada's Yukon Territory; at last, the Gold Rush was on.
