Telegraph Avenue originated from several separately named thoroughfares. In 1859, a
telegraph line was constructed between Oakland and
Martinez by the
Alta Telegraph Company, and the existing roads which ran alongside it were then renamed "Telegraph Road". The segment of the Telegraph Road which ran from downtown Oakland out to the
Peralta estate in Temescal was previously known as the "Peralta Road". The segment which ran to and up Harwood's (now Claremont) Canyon was first known as "Harwood's Road", named for William Harwood, an early Oakland politician who leased grazing land in the canyon. The Telegraph Road followed the route of present-day Telegraph Avenue from Downtown Oakland to
Temescal, then ran along what is now the route of Claremont Avenue up to the summit of the
Berkeley Hills where it became Fish Ranch Road, named some time after 1870, the year the Oakland Trout Company incorporated its fish and frog farm in the vicinity. In Berkeley, the trustees of the private
College of California (the predecessor of the
University of California) laid out a residential
subdivision south of their new campus in order to finance its construction. The streets were named alphabetically from east to west; the third street was named "Choate Street", after
Rufus Choate. Oakland subsequently extended a road to connect with Berkeley's Choate, but named it "Humboldt Avenue". Oakland's first
horsecar line was built in 1869 and ran along Telegraph Road to 36th Street. It was extended to Temescal a year later, then to the university campus via Humboldt and Choate after the university relocated from Oakland in 1873. A business district grew up along Choate and Humboldt Streets. The horsecar line was eventually replaced by a
steam dummy line, and later by an electric streetcar line. This transportation corridor stimulated the development of neighborhoods along its route, as well as an
amusement park,
Idora Park, between 56th and 58th Streets. When the segment of Telegraph Road leading up to Harwood's Canyon was renamed "Claremont" to suit the interests of a developer of the district (see
Claremont, Oakland/Berkeley, California), the cities of Berkeley and Oakland opted to change Humboldt and Choate to Telegraph since Oakland's portion of the thoroughfare was already aligned with what remained of the old Telegraph Road between the new Claremont and downtown Oakland. Since Telegraph Road was a county road, a petition to change its name to Claremont Avenue was presented to the Alameda County Board of Supervisors on January 12, 1880. The petition was granted. Although the 1880 petition included it, the segment of the old Telegraph Road that ran up the canyon to the summit of the Berkeley Hills was renamed Claremont Road by the Oakland City Council (which by then had annexed the previously unincorporated area) on February 14, 1913, acting on a petition by the owners of the
Claremont Hotel. The only discernible difference in naming was the substitution of "Road" for "Avenue" for the canyon segment. Berkeley changed Choate Street to Telegraph Avenue in 1890. ==Early-mid 20th century==
