499 Beacon is located on the south side of Beacon, between Massachusetts Avenue and Charlesgate East, with 495-497 Beacon to the east and 501 Beacon to the west.
499 Beacon was designed by architect Samuel D. Kelley and built in 1888-1889 by Keening & Strout Brothers, masons, as a four-unit apartment building for Edwin B. Horn, Jr., a jeweler and real estate developer. He is shown as the owner on the original building permit application, dated November 19, 1888, and on the final building inspection report, dated April 12, 1889. Soon after it was completed, a companion apartment house was built at 495-497 Beacon; it was built for a different owner and designed by architect Ernest N. Boyden in a style closely resembling 499 Beacon, creating a symmetrical composition.
Edwin Horn purchased the land for 499 Beacon on November 26, 1888, from Mary Ann (McCurdy) Hall, the wife of Prescott Coburn Hall. She had acquired the land on August 21, 1888, from building contractor Silas Whiton Merrill, who had purchased it on April 18, 1888, from Henry Lee, H. Hollis Hunnewell, and Augustus Lowell. The land was part of a larger parcel that Henry Lee and his partners purchased on February 20, 1883, from a real estate investment trust formed by Grenville T. W. Braman, Henry D. Hyde, and Frank W. Andrews. The parcel was one several tracts of land the trust had purchased from the Boston Water Power Company on March 1, 1872.
