Today we are highlighting some archival photographs that we recently digitized. In our archive’s stacks there is a flat box housing seven mounted photographs associated with the T.J. Flynn Metal Works Inc., a 20th century Cambridge business.

The earliest reference to the company was in 1914, when Thaddeus J. Flynn’s T.J. & Sons Co., Sheetmetal Works, was located on Albany Street in Cambridgeport. This family company witnessed many location changes from 1914 to the 1930s. In 1918 it was at 37 Albany Street, then it moved to 18-20 Portland Street in 1925, and in 1930 it was located at 49 Albany Street. By 1918, the name of the company changed to its more well-known version, T.J. Flynn Metal Works Inc.
Associated with this larger business was Flynn Roofing and Metal Co., run by Flynn’s son, Edmund T. Flynn. It also moved around the neighborhood – residing at 37 Albany Street in 1917, 8 Portland in 1920, then 35 Albany Street between 1921-1922, and subsequently 49 Albany Street in 1937. Unfortunately, none of the original buildings have photographic references in the CHC files and the larger company was officially unincorporated by 1968-1972, although its final locations are unknown.
During the heyday of the T.J. Flynn Metal Works Inc., Thaddeus married Mary A. Flynn. Their son Edmund invented a life-raft design in the early 1900s. The photographs in the CHC’s archival box are accounts of his work.

It is unknown when these images were taken since they do not reflect Edmund’s patent approved by the U.S. Patent Office on July 16, 1918. His final design notes emphasize how the official raft was “substantially pointed” at each end and that the “buoyant member is non-circular in cross-section.” The polygon version reflected in the photographic images could have been an earlier design Edmund scrapped during his tests at Scituate Harbor. Or, it could have been a later revision since his patent was updated in 1941.

Nevertheless, Edmund’s patented life-raft was a success. It was used in both World Wars and it was officially approved for use on ocean, coast, bay, lake and sound vessels by the Department of Commerce.

Thaddeus also gained a patent in 1929 for a roof drain. A year later, on September 9, 1930, Thaddeus died, and his wife Mary became president of the company. She was assisted by J. Henry Flynn and his wife Belinda S. Flynn, who were first referenced as additional owners of the company in 1925. However, by 1968-1972 the family business had dwindled out. Edmund’s son, Jonathan, opened European Engineering in Belmont, MA in 1958 but it was ultimately a failed venture. Jonathan’s son, Nick, recounts his father’s subsequent journey in “The Button Man,” published in The New Yorker in 2004.
