435 Marlborough was built in 1885 for Chadwick & Stillings, for speculative sale, one of eight contiguous houses (431-445 Marlborough). Chadwick & Stillings (N. Henry Chadwick and Oscar L. Stillings) was a hat block and flange company that became a significant house building firm in the 1880s and 1890s. They are shown as the owners, architects, and builders on the original building permit application for 435 Marlborough, dated June 16, 1885, and on the final building inspection report, dated November 13, 1886.
By the 1887-1888 winter season, 435 Marlborough was the home of Charles Sumner Eaton and his wife, Ella F. (Thompson) Eaton. They previously had lived at the Hotel Cluny at 543 (233) Boylston. They probably leased 431 Marlborough from Dr. David Williams Cheever, who is shown as the owner on the 1888 Bromley map. He was a physician; he and his wife, Anna Caroline (Nichols) Cheever, lived at 557 (239) Boylston.
Trained as an architect, Charles Eaton was proprietor of the Temperance Spa at 219 Washington Street. The Temperance Spa was a bar and restaurant that served only non-alcoholic beverages, such as mineral waters and phosphates, but provided the ambiance of a saloon. It was described at some length in an article in the July 1886 issue of Edward Everett Hale’s The Lend a Hand Magazine, which commented, in part:
“You will find Mr. Eaton if you will go any day in Boston to the ‘Temperance Spa,’ which is at no. 219 Washington Street. That is the real name on the picturesque sign, but I find people call it in practice the ‘Temperance Bar,’ and I do not see why they should not, for that is exactly what it is. It is nearly opposite the head of State Street, a small, elegant saloon, opening directly from the sidewalk, in the most crowded part of the most crowded street in Boston. I do not suppose I should say I am a habitué there, but I hardly ever pass it on foot in the middle of the day, without going in. I stopped there the other day when forty-four customers were standing as close as they could stand at the different counters, and several more, like myself, were waiting for their turn. I asked Mr. Eaton if he knew how many people had ever passed through the shop in a day, and I found that he did not. There are three entrances and it would be almost impossible to count. But I think it is certain that no other drinking-shop in Washington Street receives so many customers as the day goes by.
“It proved, indeed in answer to my wondering inquiries, that there are probably quite as many popular temperance drinks in common use in such a place, as there are of alcoholic drinks in an ordinary barroom. I counted the names of near fifty such drinks displayed on different signs with their prices, which ranged from five cents to twenty each. This does not include such cold comforts as Apollinaris, Vichy, Congress water, Star water and the like, which are however there, for anybody who wants them. There are also other drinks with fancy names, such as ‘Wide Awake,’ ‘Next Morning,’ and the like, which have been designed by physician indeed for the use of men who have drunk too hard of spirit the night before.”
In about 1900, Charles Eaton renamed his restaurant Thompson’s Spa, named for his wife’s family.
The Eatons continued to live at 435 Marlborough during the 1892-1893 winter season, but moved thereafter to Brookline.
435 Marlborough was not listed in the 1894 Blue Book.
By the 1894-1895 winter season, 435 Marlborough was the home of George Fillmore Swain and his wife, Katharine Kendrick (Wheeler) Swain. They previously had lived in an apartment at 409 Marlborough. Katharine Swain is shown as the owner on the 1895 and 1898 Bromley maps.
George Swain was a civil engineer and professor of civil engineering at MIT and then at Harvard’s Graduate School of Applied Science.
Katharine Swain died in December of 1901. George Swain married again, in January of 1904, to Mary Hayden Lord. After their marriage, they lived at 435 Marlborough. They also maintained a home in Ipswich. George Swain is shown as the owner of 435 Marlborough on the 1908 Bromley map, and Mary Swain is shown as the owner on the 1912 map.
Mary Swain died in April of 1914. George Swain married again, in August of 1914, to Mrs. Mary A. (Batchelder) Rand, the widow of Frank H. Rand. After their marriage, they lived at 1988 Commonwealth in Brighton.
435 Marlborough was not listed in the 1916 Blue Book.
By the 1916-1917 winter season, 435 Marlborough was the home of attorney Samuel Henry Hudson and his wife, Emilie E. (Potter) Hudson. They had married in 1916 and 435 Marlborough probably was their first home together. Prior to their marriage, he had lived at 96 Bay State Road. He is shown as the owner of 435 Marlborough on the 1917 Bromley map.
They continued to live at 435 Marlborough during the 1918-1919 winter season, but moved thereafter to the Hotel Vendôme.
In the spring of 1919, 435 Marlborough was acquired from Samuel Hudson by Dr. George Sherwin Clark Badger and his wife, Grace M. (Spear) Badger. The transaction was reported in the Boston Globe on March 29, 1919. They previously had lived at 48 Hereford. Grace Badger is shown as the owner of 435 Marlborough on the 1928 and 1938 Bromley maps. They also maintained a home in Cohasset.
George Badger was a physician and maintained his office at 435 Marlborough. During his career, he served as physician in chief of the New England Baptist Hospital, and also was an instructor at Harvard Medical School.
George Badger died in April of 1954. Grace Badger continued to live at 435 Marlborough until about 1958, when she moved to an apartment at 295 Beacon.
435 Marlborough subsequently changed hands and, from the early 1960s, was being operated as a lodging house, although its legal use remained as a single-family dwelling.
In October of 1981, Charles C. Patsos, trustee of the 435 Marlborough Street Trust, purchased 435 Marlborough. He continued to operate it as a multiple dwelling.
In 1991, the building was damaged by fire. It remained vacant for the next four years.
In August of 1994, Charles Patsos applied for permission to legalize the occupancy as a multiple dwelling (noting that it had been occupied as fifteen studio apartments “at least since the present applicant purchased the subject property”) and to convert it into nine apartments. He subsequently modified the project and in October of 1994, he filed for (and subsequently received) permission to convert the property into six apartments.
The property changed hands and in June of 2004 was purchased by Matthew C. Bailey, trustee of the 435 Marlborough Street Realty Trust.
In August of 2004, he converted the property into six condominium units, the 435 Marlborough Street Condominium.
