About Lionel-Max Chassin
Lived 1902 – 1970 (aged 68). Lionel-Max Chassin was a French ufologist, military personnel, french resistance fighter, aircraft pilot, soldier and military officer.
Guillaume Jean Max Chassin, known as Lionel-Max Chassin (26 April 1902 – 16 August 1970), was a French Air Force general, resister, colonial activist and supporter of Catholic extreme-right-wing politics.
Biography He was born in Bordeaux to Suzanne Meriochaud and Max Chassin, a notary. He studied at the Collège de Blaye and the Lycée de Bordeaux. He joined the École navale [Naval School] in France in 1919, taking part in naval operations during the Rif War and obtaining an engineering diploma in 1921. He graduated first from the Aeronautics School at Rochefort (Charente-Maritime) and entered the Aeronavale [Naval Air Force] in 1926, also teaching a higher course in air navigation from 1927 as a young lieutenant and becoming a director there two years later. He was a keen rugby player and an excellent shot with a rifle.
In 1935, he joined the Air Force at the time of its creation and was one of the first to qualify from the Avignon-Puault parachuting school in 1936, where he became a captain. He became president of the Air Force shooting society and of the National Military Sports Council. Chassin piloted admiral François Darlan's plane to Algiers on 5 November 1942, three days before the Allied invasion. He actively participated in negotiations during the American landing and went to Morocco and Dakar to rally French forces to the Allies' effort. Made lieutenant-colonel in 1943, he was appointed director of military personnel of the air force. At the end of his term with SHAPE he benefited from permanent aircrew leave in April 1958.
He was a leader - nicknamed le grande B - of militant nationalist Henri Martin's Grande O plot (Martin was le grande V) along with general Paul Cherrière (le grande A) which ran from 1954 to 1958. The aim of the plot, after an uprising in Algeria and France - in which Chassin would seize the Saint-Étienne arms factory and take control of Lyon - was a Catholic, corporatist right-wing state inspired by Portugal's existing Estado Novo. In January 1957, he succeeded general Raoul Salan as head of the patronage committee of the Association des combattants de l’union française (ACUF) [Association of French Union Combatants]. Because of his involvement in he counter-revolutionary Opération Résurrection, his arrest was ordered under Pierre Pflimlin's brief prime ministership and he went underground. He tried to mobilise French-Algerian partisans in opposition to the Fourth Republic. In June 1958, he founded the Mouvement populaire du 13-Mai party, which initially supported the return of Charles de Gaulle; with anger and embarrassment at party differences, including ACUF members leaving, he resigned in September, passing control to Robert Martel. He became interested in Georges Sauge's anti-communist Centre d'études supérieures de psychologie sociale (CESPS) [Centre for Advanced Studies in Social Psychology], which advocated defence of the "Christian West", attending and speaking at meetings in 1959. In January 1960, having tried to reach Algeria during the right-wing insurrection known as La semaine des barricades, he was arrested by the police but released shortly after. From 1961, his activism was cut short by serious illness but he continued as ACUF president until the beginning of 1966. That year, he co-signed an anti-communist declaration denouncing Viet Cong guerrilla aggression in South Vietnam.
Interest in ufology Chassin was passionate about the subject of UFOs. In 1957, his dismissive opinions on the perceived threat to the West after the success of the Soviet Union's Sputnik satellite were widely reported. The following year, he provided the preface to Aimé Michel's work A propos des soucoupes volantes - about flying saucers - in which he wrote: "We can therefore affirm that there really are, in the sky around us, mysterious objects" adding that their identification as distinct from enemy missiles was essential given the US reaction to Sputnik. From 1964 to 1970, he chaired the :fr:Groupe d'étude des phénomènes aériens (GEPA) [Study Group of Aerial Phenomena], a private ufological association of five hundred members. - and Claude. After Marcelle Chassin died, he remarried to Micheline Poggi-Chalais in 1961. Chassin died on 18 August 1970 in Marseille after a long illness.
