Friedrich Ludwig Bartelt (not F.A. or F.T. as variously
reported) was born on 29 May 1852 in Stettin, Prussia. He founded the Polysulphin Company, first in Brislington and then at
Keynsham, manufacturing soap for laundries. His biplane-like machine with beating wings was exhibited at the Olympia Aero
Show in March 1911. No further reports of progress appeared and it is certain that this machine was not successful.
Bartelt died on August 5 1924 in Corston Lodge, Corston, Somerset.
