"Robert Edwin Peary, Sr. (May 6, 1856 \u2013 February 20, 1920) was an American explorer who claimed to have reached the geographic North Pole with his expedition on April 6, 1909. Peary's claim was widely credited for most of the 20th century, rather than the competing claim by Frederick Cook, who said he got there a year earlier. Both claims were widely debated in newspapers until 1913.Modern historians generally think Cook did not reach the pole."@en . . . . "1856Z"^^ . . "1920Z"^^ . . . . "1856-05-06Z"^^ .
