In October 1907, Fernand Maximillian Leon Jacquet (born November 2, 1888) enlisted in the Belgian Army as a cadet. After successfully completing training at the École Royale Militaire located in Brussels, Belgium, Jacquet received his commission as an infantry second lieutenant and was posted to the 4e Régiment de Ligne (4th. Line Regiment) on June 25, 1910. Jacquet, though, soon grew very keen on aviation and towards the end of 1912, he applied for both civilian flight school as well as military flight school in order to earn his flying credentials. He received his instruction in the village of Sint-Job-in-'t-Goor and earned his civilian pilot license (license no. 68) on February 25, 1913 and then his military pilot certification on August 30, 1913. After a promotion to first lieutenant, Jacquet was posted to the 2e Escadrille d’Observation (2nd. Observation Squadron) based in Boninne, Belgium. An interesting note was that Jacquet was nearsighted and it was the main reason he always flew two-seater aircraft so that he would do the flying while his gunner would do the shooting.
When World War One began and Germany invaded Belgium in August 1914, Jacquet was in the thick of it, flying reconnaissance missions from his unit's Boninne base, to include deep penetrations behind German lines. He also took it upon himself to bomb German positions whenever possible, hitting German targets at Groote Hemme on November 24, 1914 and twice on December 24, 1914 at Beerst and Essen. At this time, Jacquet's mount was a Farman HF.20 pusher reconnaissance aircraft and it was on this aircraft and his later Farman F.40 aircraft that would carry the grim moniker of the death's head on the nose. On April 17, 1915, Jacquet scored Belgium's first aerial kill when his gunner Henri Vindevoghel shot down a German Aviatik reconnaissance plane. Sometime in 1916, Jacquet traded in the HF.20 for an improved F.40 mount. Like the HF.20, it was a two-seat pusher-style reconnaissance aircraft but while slower and with less range than the HF.20, the F.40 had a better service ceiling, had better armament, and in addition to a better bomb load, could carry ten Le Prieur rockets. During the course of the war in 1916, Jacquet and his gunner, Louis Robin, racked up another three kills though, on September 8, 1916, their F.40 was shot down by German anti-aircraft fire. Fortunately, while the F.40 was utter wreckage, both men walked away unscathed. In December 1916, Jacquet was given command of the 1ère Escadrille de Chasse. On February 1, 1917, Jacquet became an ace when Robin downed a German Rumpler aircraft while Jacquet was flying a two-seat Sopwith 1 1⁄2 Strutter and by December 1917, Jacquet was promoted to Captain-Commandant and put in charge of the Groupe de Chasse, Belgium's first fighter wing. By now, Jacquet was flying the two-seat SPAD S.XI with his unit being a mixture of the SPAD S.XI and Sopwith 1 1⁄2 Strutters.
When the war ended, Jacquet had seven confirmed victories with another nine unconfirmed and he had an impressive array of medals to go with his wartime service. His decorations included being a Knight of the Order of Leopold (Chevalier de Ordre de Léopold), Ordre de la Couronne avec des Palmiers (Order of the Crown with Palms), the Croix de Guerre (six citations), Médaille de la Victoire 1914-1918, Médaille Commémorative de la Guerre 1914-1918, Knight of the Legion of Honor (Chevalier de Légion d'Honneur), the Croix de Guerre (the French version), the Russian Order of St. Anna (Орден Святой Анны), and the British awarded him the Distinguished Flying Cross (the only Belgian to have received this decoration during World War One).
The photograph depicts Jacquet (on the left) with his gunner, Lt. Robin. Jacquet's rank is that of Captain as shown by the three stars on his collar tabs. The fuselage of his F.40 was all black with a predominantly white skull on the nose. The F.40 was a tall aircraft, standing 12.1 feet in height, had a length of 30.4 feet, and a wingspan of 57.9 feet. The F.40 used many engines but the most common was a Renault V-12, air-cooled piston engine that developed 130 horsepower that drove a 2-bladed, fixed pitch wooden pusher propeller. This gave the F.40 a maximum speed of 84mph at 6,600 feet. Enough fuel was carried for a 260 mile range or a total air endurance of 2 hours and 20 minutes. The service ceiling was 13,290 feet and it took the F.40 a total of fifteen minutes to reach 6,600 feet. For weapons, the usual fit was a single .303 caliber Lewis machine-gun though it could be fitted with two. A total of 530 pounds of bombs could be carried and the F.40P model could mount ten Le Prieur air-to-air incendiary rockets. These rockets were exclusively used against observation balloons and German Zeppelin airships.
Jacquet retired from the Belgian military in 1921 after fourteen years of service. He, along with Louis Robin, opened a flying school in Gosselies, Belgium. On August 27, 1931, Jacquet became the commercial director for the British aviation firm Fairey's Belgium subsidiary Société des Avions Fairey that the British company had set up at Gosselies' aerodrome. When the Germans, again, invaded Belgium on May 10, 1940, Jacquet once again heeded the call to battle and joined the Résistance Belge (Belgian Resistance) at the age of 52. He was captured by the Germans and imprisoned at Fort de Huy in the city of Huy in 1942. The fort was used by the Germans to house all manner of criminals, communists, resistance fighters, captured soldiers from England, France, and Russia, and even hostages for one reason or another. It was also used as a transit stop for Jews and other "undesirables" before being taken to either the Neuengamme concentration camp in northern Germany or the Vught concentration camp in the Netherlands. Jacquet survived imprisonment and was freed from Fort de Huy upon the end of the war. He moved to Leval-Chaudeville and that was where he passed away on October 12, 1947 at the age of 58.
