Maginnis & Walsh

Architects Charles Donagh Maginnis (1867-1955) and Timothy Francis Walsh (1868-1934) founded the architectural firm Maginnis, Walsh and Sullivan in 1898, along with Matthew Sullivan (1868-1938). In 1906, Sullivan left the firm, and the name changed to Maginnis & Walsh. The Boston-based firm, and its successive iterations, known for its ecclesiastical design, was commissioned to design hundreds of churches, seminaries, college and university buildings, and hospitals throughout New England and beyond. Eugene F. Kennedy Jr. (1904-1986) joined the firm in 1926, becoming a partner in 1941 as reflected in the firm’s name change to Maginnis, Walsh and Kennedy. In 1969, the firm further evolved to be known as Kennedy and Kennedy Architects, with Kennedy naming his brother chief partner.

Processing Information

This collection is minimally processed. In 2023, Archivist Margaret Peachy converted an existing collection inventory into a finding aid and added collection level description. The pre-existing inventory listed each architectural project (commission) represented in the collection and included commission numbers, building addresses, alternative building names, building descriptions, clients, project histories, and project phases. This information was transferred to the Scope and Contents note for each commission, using a structured formula. “Unidentified” is used to indicate blank fields from the original inventory. Peachy derived extent information for each commission from the inventory’s count of rolls, folded bundles, and specification files, but did not confirm extents against the physical materials. The finding aid is not inclusive of all materials found in the collection, since the pre-existing inventory did not include photographs or business records. No physical processing took place at the time of finding aid creation.

Processing Information

This electronic finding aid is transcribed from legacy data. In many cases, transcriptions were not verified against collection materials at the time of transcription. As a result, this finding aid could be incomplete and might only reflect a partial understanding of the material.

Statement on harmful description

Archival description reflects the biases of time periods and cultures in which it was created and may include direct quotations or descriptions that use inappropriate or harmful language. Creator provided descriptions may be maintained in order to preserve the context in which the collection was created and/or used. Legacy description and potentially offensive content may be made available online until a collection can be reprocessed because the access that they provide to primary source materials is uniquely valuable to the research community at large. Our efforts to repair outdated descriptions and to describe our collections more equitably are iterative and ongoing.
