Caspar William Whitney (September 2, 1864 – January 18, 1929)[1] was an American author, editor, explorer, outdoorsman, and war correspondent.

From 1900, he was an owner and editor-in-chief of the monthly Outing magazine, which promoted the outdoors and sporting pursuits, as well as a good deal of adventure fiction; authors included Jack London and Clarence E. Mulford.

He wed Anna Childs in 1889; after he departed for the Arctic Circle in December 1894, a trip he would later describe in his book On Snow-Shoes To The Barren Grounds, she filed for divorce, which was granted in Oklahoma in January 1895.

[8][9] He was married a third time in 1909, to Florence Canfield Whitney, who like him did relief work in Belgium during World War I.

[10] Caspar Whitney wrote a biography of Florence's father, the colorful miner and industrialist Charles A. Canfield (1848–1913), in 1930.
