412 Beacon was designed by Shaw and Hunnewell, architects, and built in 1887 by Lyman D. Willcutt, builder, as the home of Charles Head and his wife, Clementine Hortense (Lovering) Head. They previously had lived at 231 Beacon. Charles Head is shown as the owner of 412 Beacon on the original building permit applications for the house and for a stable at the rear, both dated February 15, 1887, and on the 1888 and 1908 Bromley maps.
Charles Head was a banker and stockbroker, and served as President of the Boston Stock Exchange.
The Heads also maintained a home, Headlands, in Westport, New York.
Hortense Head died in April of 1909 and Charles Head died in January of 1910.
The house was not listed in the 1911 Boston Blue Book. Charles Head’s Heirs are shown as the owner on the 1912 Bromley map.
By the 1911-1912 winter season, it was the home of shoe manufacturer Henry Bradford Endicott and his wife, Louise (Clapp) Colburn Endicott. They had lived at the Hotel Touraine (southeast corner of Boylston and Tremont) during the previous season. Their primary residence was in Dedham. They continued to live at 412 Beacon through the 1913-1914 season.
By the 1914-1915 winter season, 412 Beacon was the home of William Bradford Homer Dowse and his wife, Fanny Lee (Reed) Dowse. They previously had lived in West Newton. Fanny R. Dowse is shown as the owner og 412 Beacon on the 1917 Bromley map. They also maintained a home in Sherburne.
William Dowse was a lawyer and business executive. He was president of Reed & Barton Manufacturing, the United States Fastener Company, and several other manufacturing companies.
By 1927, 412 Beacon was owned by Dr. William Russell MacAusland and his brother, Dr. Andrew Roy MacAusland, both physicians and orthopedic surgeons, who previously had their medical offices at 240 Newbury.
In 1927, they converted the property into doctor’s offices for themselves and other doctors, including adding two stories to the building and lowering the entrance to street level. The remodeling was designed by Thomas M. James Company, architects. Plans for the remodeling are included in the City of Boston Blueprints Collection in the Boston Public Library’s Arts Department (reference BIN P-50).
W. R. and A. R. MacAusland, et al, trustees, are shown as the owners on the 1928 and 1938 Bromley maps.
William Russell MacAusland and his wife, Dorothy (Brayton) MacAusland, lived at 230 Marlborough. Andrew Roy MacAusland and his wife, Katharine (Brayton) MacAusland, lived at 218 Commonwealth. Dorothy and Katharine MacAusland were sisters.
By the 1930s (and probably before) they had installed a metalworking shop at the former stables at rear of the building where they made orthopedic devices for their patients.
In August of 1944, their agent, the Boston Safe Deposit Trust Company, applied for (and subsequently received) permission to store 500 gallons of gasoline on the property for use by doctors who maintained offices in the building.
Both Drs. MacAusland continued to maintain their offices at 412 Beacon until about 1951. In that year, Andrew MacAusland moved his office to his home at 218 Commonwealth. William MacAusland continued to maintain his practice at 412 Beacon until his death in August of 1965.
By the mid-1960s, 412 Beacon was owned by Frances (Baker) MacAusland (the wife of William MacAusland’s son, William, Jr., also an orthopedic surgeon) and Hildreth M. Clark, as trustees of the 412 Beacon Trust.
The property remained a medical building, called the MacAusland Building, until the early 1980s.
In February of 1983, John V. O’Neil, trustee of the 412 Waterside Trust, purchased 412 Beacon from Dr. William MacAusland, Jr., and his son, Theodore B. MacAusland, the current trustees of the 412 Beacon Trust.
In March of 1983, the 412 Waterside Trust applied for (and subsequently received) permission to convert the property from doctor’s offices into eleven apartments. In October of 1983, it converted the property into ten condominium units, the 412 Beacon Street Condominium.
In June of 1987, the Trust applied for (and subsequently received) permission to reduce the legal occupancy from eleven to ten units, noting that was the number of units originally constructed in 1983.
