393 Commonwealth is located on the north side of Commonwealth, between Massachusetts Avenue and Charlesgate East, with 391 Commonwealth to the east and 395 Commonwealth to the west.
393 Commonwealth was designed by Little and Browne, architects, and built in 1899-1900 by Francis F. Morton, builder, for Josephine (Moore) Dexter, the widow of Chicago attorney Wirt Dexter. She is shown as the owner on the original building permit application, dated June 5, 1899.
The rear of the lot on which 393 Commonwealth was built extends north to Marlborough Street and has a secondary street address of 442 Marlborough.
Josephine Dexter purchased the land for 393 Commonwealth on May 12, 1899, from the estate of Abbott Lawrence. He had purchased the land on January 18, 1886, from a real estate investment trust formed by Francis W. Palfrey, Francis A. Osborn, and Grenville T. W. Braman, part of a tract of land the trust had purchased on June 1, 1880, from the Boston Water Power Company. When they sold the lot to Abbott Lawrence, the trustees included language prohibiting the use of any building on the land as a stable and prohibiting the erection of any building of more than one story in height within thirty feet of Marlborough.

By the 1900-1901 winter season, Josephine Dexter had made 393 Commonwealth her home. Her daughter, Katharine Moore Dexter, lived with her. They had moved to Boston in early 1896 and had leased Arthur Little’s home at 2 Raleigh (he and his wife, Jessie Maria (Whitman) Means Little, were living at their home in Swampscott). A January 26, 1896, note in the Chicago Tribune reported that “Mrs. Wirt Dexter has given up her house in Chicago and has gone to live permanently in Boston,” and a Boston Globe “Table Gossip” item on the same day commented that “Mrs. Wirt Dexter of Chicago has taken Mr. Arthur Little’s house in Boston for the remainder of the winter, desiring to introduce her daughter to her Boston friends.”
Katharine Dexter graduated from MIT in 1904 and in September of that year married Stanley R. McCormick, son of Cyrus McCormick, inventor of the reaper and founder of the International Harvester Company. After an extended trip in Europe, they spent they 1905-1906 winter season in Chicago and then leased a house in Brookline. They spent the 1906-1907 winter season at 393 Commonwealth with her mother. They also maintained a residence in Marion on Buzzards Bay.
Stanley McCormick suffered from attacks of mental illness and, in June of 1908, he was placed under a doctor’s care in Montecito, California. In April of 1909, Katharine McCormick, his doctor, and the McCormick family lawyer were named his guardians. He continued to live in Montecito until his death in January of 1947.
By the 1909-1910 winter season, Katharine McCormick had resumed living with her mother at 393 Commonwealth. She also maintained homes in New York and Santa Barbara. She was an active advocate of woman’s suffrage (as was her mother) and strong supporter of women’s education, the League of Women Voters, and family planning.

In 1962, at the suggestion of her friend Adlai Stevenson, she donated Prangins to the US government, for use by the US diplomatic mission in Geneva.
