E. Johnson, with a wrap-around porch and a rear carriage house.","why_significant":"The nomination argues local significance in architecture and science. The house is a good local example of Stick-Eastlake residential design and one of very few formal Victorian homes left in its neighborhood. It is also tied to Dr. Edwin Hennessey, a prominent Napa physician and long-time County Physician who experimented with the x-ray in the 1890s.","narrative":"Built in 1889, this two-story wood frame house at 1727 Main Street in Napa shows the Stick-Eastlake style. Its features include a square front bay with a projecting gable and pierced bargeboard, bays on three sides, and a heavy wrap-around porch with turned posts and pierced brackets, added about 1901. Inside, a first-floor game room has hand-painted floral designs on pressed tin walls and ceiling, along with an original art glass light fixture. A two-story carriage house stands behind the residence. The house was designed by M. E. Johnson and is one of very few formal Victorian homes left near the edge of the old downtown. It is also linked to Dr. Edwin Hennessey, who came to Napa in 1886, served as County Physician from 1889, and was appointed physician of the Yountville Veterans Home in 1896. In 1897 he experimented with the x-ray, locating gems in rocks and a bullet lodged behind a man's jaw. Later changes, such as the enclosed rear porch and concrete front steps, are judged not to harm its integrity.","period_of_significance":"1800-1899","architect_builder":"M. E.
