Weissmann et Marx

French patent agents Weissmann et Marx (sometimes with the former partner spelled with one "s", Weismann) advertised their address as 90 rue d'Amsterdam, Paris. Telephone 111.16..

It seems they communicated, twice at least, the list of aeronautic patents to L'Aérophile (see [1], [2]).
