Thomas Stewart Negus trained in England. He worked with his brother, John David Negus, at the Washington Observatory trials in 1886. It is stated Thomas was established in 1848. They worked from various addresses in New York, but appear to have moved to 100 Wall Street in 1869. Tony Mercer comments that most of their movements conform with Lancastrian workmanship.
