The Pasadena and Mount Wilson Toll Road Company, incorporated in 1889 by Judge Benjamin Eaton and others, was reorganized in 1890 with the purpose of building a ten mile wagon road from Eaton Canyon up the west flank of the San Gabriel Mountains to Mt. Wilson, above Pasadena, California. The road was completed and put into use in 1891, and the company gradually acquired control of the Mt. Wilson area. A syndicate took control in 1904, and the Mt. Wilson Hotel was built. The road was later improved for automobile traffic and continued in use until its closure in 1936. The Mount Wilson Toll Road Company then became the Mount Wilson Hotel Company.
