Question: When was the French aircraft industrialist partially responsible for developing the Potez VII born?

Context paragraphs:
Potez SEA VII: The Potez SEA VII, otherwise known simply as the Potez VII, was an early airliner developed in France shortly after the First World War.  It was a civil version of the SEA IV military aircraft that Henry Potez had developed with Louis Coroller and Marcel Bloch as the Société d'Etudes Aéronautiques.  With the end of hostilities, the French military cancelled its orders for the SEA IV and the company dissolved.  Potez, however, believed that the design had potential in peacetime and founded Aéroplanes Henry Potez in 1919 to refurbish war-surplus machines for civil use.  This soon led to a revision of the design as the SEA VII.  This differed from its predecessor in having an enclosed cabin for two passengers occupying the rear fuselage.  The wings were enlarged to reduce their loading and therefore to allow for slower, gentler landings than the military aircraft had been capable of making.

Marcel Dassault: Marcel Dassault (born Marcel Bloch; 22 January 1892 – 17 April 1986) was a French aircraft industrialist.

Potez 24: The Potez 24 A.2 was a mid-1920s French sesquiplane intended to replace the Potez 15 as an army observation aircraft.  The further improved and larger Potez 25 was preferred for production.

Potez 50: The Potez 50 or Potez 50 A2 was a French two seat military multi-rôle aircraft, first flown in 1931.  It did not go into service but seven variants using five different engines were produced, one of them setting several speed with useful load records and another, the Potez 506, setting three altitude world records.

Potez: Potez (pronounced ] ) was a French aircraft manufacturer founded as Aéroplanes Henry Potez by Henry Potez at Aubervilliers in 1919.  The firm began by refurbishing war-surplus SEA IV aircraft, but was soon building new examples of an improved version, the Potez VII.

Potez 36: The Potez 36 was a French two-seat touring or sport monoplane designed and built by Potez.  The Potez 36 was a high-wing braced monoplane with a conventional landing gear.  It had an enclosed cabin with side-by-side seating for a pilot and passenger.  The design had some unusual features like folding wings to make it easier to store or to tow behind a motor car.  Some of the aircraft had Potez-designed leading-edge slats.  The aircraft was popular with both French private owners and flying clubs with a small number being used by the French Air Force during the 1930s as liaison aircraft.

Potez 25: Potez 25 (also written as Potez XXV) was a French twin-seat, single-engine biplane designed during the 1920s.  A multi-purpose fighter-bomber, it was designed as a line aircraft and used in a variety of roles, including fighter and escort missions, tactical bombing and reconnaissance missions.  In the late 1920s and early 1930s, Potez 25 was the standard multi-purpose aircraft of over 20 air forces, including French, Polish and .  It was also popular among private operators, notably mail transport companies.

Société d'Études Aéronautiques: The Société d'Études Aéronautiques (SEA) ("Society for Aeronautical Studies") was a French aircraft manufacturer founded in 1916 by Henry Potez, Marcel Bloch, and Louis Coroller at Suresnes.

Henry Potez: Henry Potez (Méaulte, 30 September 1891 – Paris, 9 November 1981) was a French aircraft industrialist.

Potez 452: The Potez 452 was a French flying boat designed and built by the French aircraft company Potez in response to a French Navy specification for a shipboard reconnaissance machine for use on its battleships and cruisers.
