Albert Sieber (1843-1907) "was a German-American military figure, prospector, and Chief of Scouts during the Apache Wars.
Sieber was severely wounded on July 2, 1863 in the Battle of Gettysburg, specifically the Cemetery Ridge engagement. After the war, he was a prospector in California, Nevada, and then ended up in Arizona Territory, where he managed a ranch from 1868 to 1871."
General George Crook hired him to be Chief of Scouts in 1871 for much of the Apache wars.
In 1883 Crook went into the Sierra Madre of Mexico following Geronimo. Sieber was Crook's lead civilian scout and mentor to Tom Horn, whom he taught to speak German. Sieber was in the field but not present when Geronimo surrendered to Lt Charles B. Gatewood and General Nelson Miles in 1886.
Sieber was killed during a construction accident on February 19, 1907 at the San Carlos Apache Indian Reservation, then under the supervision of another famous frontier scout, "Yellowstone" Luther Kelly at Apache Trail, Gila County...
