From Wings of Linen

Société Provisoire des Aéroplanes Deperdussin built the early model TT, but the founder, Armand Deperdussin, was jailed in 1913 on fraud charges and engineering fell to Louis Bechereau. A syndicate led by Louis Blériot acquired the company and changed the name to Société Anonyme pour l'Avation et ses Derives or -- as it is popularly known, SPAD.[1]
