Description
The “Ja. Long, Royal Exchange, London" inscription on this five-section draw-tube telescope is that of James Long, an optician who was apprenticed to Edward Nairne in 1769; by 1781 he was in business as an optician at the Royal Exchange, and he remained there until his death in 1811. According to a paper inside the cap: "This tube and eyepiece, bought in London 1839. The 2-1/8" objective was figured by Henry Fitz.” Henry Fitz, Jr. was the first successful commercial telescope maker in the United States, and it was he who owned this instrument.
