Seraphim Masi

In 1822 he advertised in the Washington Directory as a "Watchmaker and Jeweler" who sold silver work, spectacles and "a variety of other fancy goods."

In 1827 he was listed in the city directory as having his shop on the north side of Pennsylvania Avenue between 4 1/2 and 6 West.

A letter from the United States Treasury Department, dated March 22, 1884, i.e., shortly after his death, appears to indicate that he had been receiving a pension as a veteran of the War of 1812.

In addition to his other creations, Masi also held a contract to attend, regulate, and repair the clocks of the United States Senate.

Masi married Catherine Agnes Bradford on November 8, 1825, and was buried in the Mount Olivet Cemetery in Washington.
