John E. Muldoon, a furniture designer and self-taught architect, was born in East Cambridge in November 1864, the first child of William H. and Catherine (McKeever) Muldoon. William had been born in the neighborhood in 1840. When the Civil War began in 1861, the 21-year-old enlisted as a private in the U.S. Army; in 1864, during the long Siege of Petersburg, Virginia, William suffered a severe wound to his left arm, which was so damaged it had to be amputated. He was mustered out that same year and returned to Cambridge; he was home when John was born. The family lived on Fifth Street in East Cambridge; John’s only sister, Sarah, was born in 1866, his brother Samuel in 1872, and his youngest brother, William, in 1888. William the father worked at the nearby New England Glass Company, and later opened a tavern, “The Cosmopolitan,” on Cambridge Street, and even became a teacher. He died in 1898.

John Muldoon attended local public schools and was apprenticed as a carpenter while a young man. In 1887, he married Margaret A. Fay; the next year, they welcomed a son, called Willie. John began work as a furniture designer for the esteemed firm of Irving & Casson and could walk to work from his home, a double house he rented with his parents on Fifth Street.

John was hired by his landlord to design and oversee construction of a new double-house to replace the existing building there. This would be John’s first known foray into the architecture field. The double house at 41-43 Fifth Street was built with modest proportions but exhibits more detail than many surrounding tenements of the time. Today many of the building’s Classically inspired elements are covered in vinyl siding, yet Muldoon’s affection for Classical design is still apparent in the original pilasters in the Ionic style that frame the two entrances under deeply overhanging eaves. An image from the 1960s (below) shows the original pilaster detailing at the bay windows with swags in the entablatures. He and his young family would occupy one unit with his mother and father living in another unit. This first known building commission for John Muldoon would set off a short, yet significant career as an architectural designer in Cambridge.

In 1892 John Muldoon, with no architectural training or academic degree, submitted the lowest bid for a new firehouse in East Cambridge and was awarded the contract. The brick structure, described in newspapers as being in the “Doric style,” was built on the corner of Otis and Third streets across from the Middlesex County Courthouse. The station, with its 85-foot hose drying tower, space to accommodate six horses, and (ironically) a smoking room for the firefighters, stood for just three years: in 1895 it and the rest of the block bounded by Cambridge, Otis, Second, and Third streets were razed to make way for the new Middlesex County Registry of Deeds.

Muldoon was then hired by the City to design another fire station just a few blocks away at the corner of Gore and Third streets. Architecturally, the second station shares many similarities with the earlier building with a stronger emphasis on Colonial Revival design with bold pilasters and pediment. Historically, the building also exhibited a Palladian window on the second floor. The former station stands today as a noteworthy institutional project in Muldoon’s early architectural career and is likely to have gained him important future commissions in Cambridge, despite his lack of professional credentials.


Muldoon’s first major project outside East Cambridge came in 1894 when a young couple James and Mary Heffernan hired him to design a large residence at the corner of Cambridge Street and Highland Avenue. The dwelling, while clearly Colonial Revival in its detailing, features a more traditional Queen Anne corner tower capped with a conical roof. Its prominent site and handsome design may have helped Muldoon attract the attention of affluent Mid and West Cambridge residents, who might otherwise have overlooked the work of a furniture designer from modest East Cambridge. Upper- and middle-class residents took notice of Muldoon’s high-quality designs, which were as good as those of major architectural firms—and cost a lot less.

In 1895 while overseeing the construction of the second fire station, Muldoon was hired by Jeremiah W. Coveney, a former undertaker, Cambridge City Councillor, and State Senator, to design a dignified single-family home at the corner of Otis and Sixth streets. The design stood out in East Cambridge: a single-family detached house was a rarity in the dense neighborhood of tenements and rowhouses as were houses in the Colonial Revival style. The symmetrical design features two-story rounded bays flanking the central entry portico with a Palladian window above. Alterations in 1992, when the building was used as a funeral home, obscured some of the original detailing, but the Colonial Revival motifs largely remain intact.


From 1895, John suffered a series of personal tragedies which put most of his projects on hold. In 1895 John and Margaret’s only child, Willie, died of diphtheria at age six. A year later, Margaret died while in Saratoga Springs, New York. After their deaths, John accepted a few small jobs in East Cambridge such as alterations to a neighbor’s house on Fifth Street, two renovations on Otis Street, and designing a stable on Gore Street (since demolished). In 1898 John lost his father.
During these somber years, John met Ellen Frances O’Connell (1875-1920), a first-generation Irish immigrant who lived with her father and mother in East Cambridge. Her father, John Patrick O’Connell, was for years the advertising agent for the Sacred Heart Review, a prominent Catholic publication that was active from 1888 to 1918. John and Ellen married in 1900 and would have six children together: five daughters (Helen, Catherine, Mary, Sarah, and Betty) and one son, John E. Muldoon, Jr.
The year before the marriage, Thomas J. Casey, the Chief of the Cambridge Fire Department, commissioned John to design a residence for his family on Lexington Avenue. The Casey’s stately, Colonial Revival double-house, a stone’s throw from the recently built Engine 9 Fire Station (1896), which was not designed by Muldoon. The Casey Residence exhibits Muldoon’s exceptional understanding on Colonial-inspired design with its rounded bays, a columned portico, and intricate trim detailing on the façade and dormers. Inside, five types of wood were laid as flooring in distinct patterns and colors.

John’s craftsmanship (and low costs) impressed developers in Mid-Cambridge, who commissioned him to design multiple properties in the neighborhood. In 1901 he designed three adjacent double-houses at 27-29, 31-33, and 35-37 Highland Avenue for the owner-developer John Elston. The three unique residences are an eclectic blend of Queen Anne and Colonial Revival influences and today are in varied states of preservation. Elston also hired Muldoon that year to design a duplex at 14-16 Ellsworth Park, a short dead-end street.



During his career designing buildings all over Cambridge, John remained employed as a designer at Irving & Casson. Though he split his time between roles as architect and designer, his employers at Irving & Casson must have given him their blessing; as in 1903, John was hired by them to plan and design a four-story, four-bay addition to the company’s plant, that would be modest in size and located in the central corridor screened from Otis and Thorndike streets.

John Muldoon’s last known project in Cambridge was the two-family house he designed for himself and his family. In 1909 he purchased a house lot on Lexington Avenue from the heirs of his former client, Fire Chief Thomas J. Casey and erected the grand Colonial Revival style structure one sees today. The two-family house boasts a large, gambrel roof with its gable end facing the street, elaborate columned porticos surmounted by balustrades topped with urns, and bold corner quoins.

John Muldoon’s legacy in Cambridge cannot be overstated. He progressed from carpenter’s apprentice and furniture designer to a twenty-year career designing houses and buildings in Cambridge. Some of the city’s best examples of Colonial Revival-style houses were designed and built by Muldoon, the self-taught architect.
While he seemingly retired from the architecture profession following the completion of his own home on Lexington Avenue, he remained employed at Irving & Casson until his death in 1937. He was 72 years old.
