A. B. Rogers

Albert Bowman Rogers (28 May 1829 – 4 May 1889), commonly known as Major A.B. Rogers, was an American surveyor now best remembered for his discovery of the Rogers Pass in British Columbia, Canada. He also has the distinction of having Rogers Pass in the U.S. state of Montana named after him, following his description of the pass in 1887.

Born in Orleans, Massachusetts in 1829, he attended Brown University, but transferred after one year to Yale University, where he obtained a degree in Engineering. Rogers served with the U.S. Cavalry during the Indian Wars, attaining the rank of major during the 1862 Dakota Sioux uprising.

His initial engineering experience was primarily on the American prairies surveying for the Chicago, Milwaukee, St. Paul and Pacific Railroad. Nevertheless, James Jerome Hill of the Canadian Pacific Railway hired Rogers in April 1881 to find a rail route through the Selkirk and Rocky Mountains. Rogers carefully studied the reports of earlier surveyors, particularly those of Walter Moberly from 1865. Moberly's assistant Albert Perry had previously described the approach to a potential pass from the Columbia River along the Illecillewaet River. In later years, Moberly claimed the pass should have been named Perry's Pass.
