This museum showcases the three nautical instrument companies run by John Bliss (1795-1857) and his descendents. I'm from a different branch of the family, so am not one of his descendents. The three companies are BLISS & CREIGHTON (1835-1853), JOHN BLISS & SON (1853-1857), and JOHN BLISS & CO. (1857-1956), all of New York City. James Bliss Marine of Boston is a different company (also founded in 1835) with no connection to the New York companies. James Bliss was acquired by West Marine.
I have provided this internet museum on the assumption that others will find this information as interesting as I do. Apparently many do, and I appreciate your positive comments.
