The story
Founded by Pierre Mauboussin in 1928, in rue de Choiseul.1
Pierre Mauboussin had been in partnership with Louis Peyret from 1928 and had jointly designed three types of light sporting aircraft. Mauboussin left the firm in 1933 after the death of Peyret and established his own aircraft design company. The company was acquired by Fouga in 1936, but continued to produce further designs until 1948.
