He was the son of Congressman Charles C. B. Walker (1824–1888). He attended Corning Free Academy, and during one year Hamilton College. Then he engaged in horse and cattle breeding on a farm in Palmyra; and in the lumber business.
In November 1891, he lost the senatorial election to his Republican opponent Franklin D. Sherwood, but Sherwood was declared ineligible for being Park Commissioner of Hornellsville, and Walker was seated by a vote of the Democratic majority of the State Senate. He was a member of the New York State Senate (27th D.) in 1892 and 1893. He died about six weeks after the end of the session, on June 6, 1893, at his home in Corning, from a "spinal affection".
