As I noted here before, a pre-1915 "blimp" was found by ADS member David Shulman. He can be contacted at the St. Nicholas Home, Brooklyn, (718) 238-8141, from 7-9 p.m. I also posted that LOST CHORDS "1906 jazz" error here, in 1999. Ken Burns must have lifted that error for his book and documentary, because Burns also used 1906.
