245 Marlborough was designed by Cabot and Chandler, architects, and built in 1883 by Woodbury & Leighton, builders. It was built as the home of dry goods merchant (and former East India merchant) George Richards Minot and his wife, Harriet (Jackson) Minot. In 1882, they had lived at 36 Commonwealth.
They also maintained a home, Woodbourne, in West Roxbury.
George Minot is shown as the owner on the original building permit application, dated June 4, 1883. He died in December of 1883, probably before the house was completed. His brother, William Minot, Jr., et al, trustees are shown as the owners of 245 Marlborough on the 1888 and 1898 Bromley maps.
Harriet Minot lived at 245 Marlborough until her death in December of 1886.
After her death, 245 Marlborough remained the home of the Minots’ son, George Richards Minot, Jr., and their five unmarried daughters: Elizabeth Sedgwick Minot, Harriet Jackson Minot, Sarah Cabot Minot, Mary Minot, and Elizabeth C. Minot.
George Minot, Jr., married in October of 1890 to Agnes Olney; after their marriage they lived at 16 Hereford. He was a dry goods merchant in his father’s firm. His sisters continued to live at 245 Marlborough during the 1895-1896 winter season, but were living elsewhere during the next two seasons.
During the 1896-1897 winter season, 245 Marlborough had become the home of merchant George Dudley Howe and his wife Alice Lloyd (Greenwood) Howe. They had lived at the Hotel Agassiz at 191 Commonwealth in 1894, and by the 1897-1898 season had moved to 179 Commonwealth.
During the 1897-1898 winter season, 245 Marlborough was the home of iron and steel merchant Barthold Schlesinger and his wife, Mary (McBurney) Schlesinger. Their principal residence was Southwood on Warren Street in Brookline.
By the 1898-1899 winter season, 245 Marlborough had once again become the home of the five unmarried Minot sisters. They also maintained a home in Bar Harbor.
Charles S. Rackemann et al, trustees are shown as the owners of 245 Marlborough on the 1908, 1917, and 1928 Bromley maps.
Sarah Minot died in January of 1903. Mary Minot died in August of 1919. Harriet Minot died in February of 1925. And Elizabeth Minot died in December of 1926.
Louisa Sedgwick Minot continued to live at 245 Marlborough until her death in March of 1932.
By the fall of 1932, 245 Marlborough was owned by Elliott Henderson. In September of 1932, he applied for (and subsequently received) permission to remodel the house and convert it from a single-family dwelling into six apartments. Although the application was granted on appeal, he abandoned the permit.
The house was not listed in the 1933-1935 Blue Books, and was shown as vacant in the 1933-1935 City Directories.
By 1934, 245 Marlborough was owned by Henry C. Brookings. In November of 1934, he applied for (and subsequently received) permission to convert the property from a single-family dwelling into a private school.
In December of 1934, 245 Marlborough was acquired from Henry Brookings by the Chandler-Marlborough School. The school was affiliated with Northeastern University and described in a December 10, 1934, letter to the Building Department from Frank P. Speare, President of Northeastern, as “attended by young ladies from eighteen to twenty-five studying secretarial science.” He assured the Building Department that there would be “no laboratories or machinery other than simple office appliances.” He also noted that the “building has never been wired for electricity” and the school “would be putting in a complete installation in a first-class manner as approved by the Edison Company.”
