After achieving a certain fame in the European Avant-garde circles in the 1970s, he founded Inism in 1980 (Paris, Café de Flore, 3 January). At the end of the 1970s and beginning of the 1980s authors such as Antonio Bueno, Primo Conti, Jean-Paul Curtay, Febo Delfi, Nino Palumbo and Philippe Soupault began to show an interest, both in Italy and abroad, in presenting, illustrating and translating some of his poems written in youth, but by this time he had definitely turned to abstract poetry; in his Neo-Greek edition of selected poems Ekloghí Piimáton (Athens, 1981), Demetris Armaos speaks of "Bertozzi's pre-history", "The Pre-history of INI". However, various anthologies have subsequently published his abstract poems, one of the most important being Mario Lunetta's Verso Roma /Roma in versi (Rome, 1986).

Bertozzi had been present as a character in several novels such as Un Uomo fuori del tempo by Lino Battista (traditional novel), Rimbaud en Abyssinie by Alain Borer (novel/essay) Jonas by Isidore Isou (hypergraphic novel), Città by Angelo Merante (innist novel) and Le Roman de Chieti by Roland Sabatier (object novel) before publishing his own first novel (an book object) Valenciennes (Paris-Florence, 1981) followed by Ci-annexé (Paris-Rome, 1983). He has also produced many poem objects. He appears as a character in the inist film San Remo by Pietro Ferrua and as main character in Bertozzi by Kiki Franceschi and in the recent Pour et contre Bertozzi by Isidore Isou (Portland, Avant-Garde Publishers, 1987) - a new Italian edition was published in 1991 and up-dated by Sandro Ricaldone for the "Opuscola" series (Sileno, Genoa). He has also been the inspiration for works by Laura Aga-Rossi, Albert Dupont, Maurice Lemaitre, Gaetano Marinò, Argentina Capriotti, Eugenio Giannì, Giovanni Agresti and Francois Proïa (the latter, apart from the well-known painting Una sola multitudini, has also dedicated to Bertozzi the recent film, INI soit qui mal y pense. De Rimbaud à Bertozzi). Important studies are being published on his work which is also the subject of various university theses.

In spite of the notable differences that exist between Inism and contemporary movements or groups, other international avant-garde figures have established close contacts with Bertozzi.

Bertozzi, who is a university professor and editor of the journal Bérénice (33 numbers in the first series and 6 in the new series), has been present at most of the inist exhibitions that have represented the main moments of expansion of this international movement in its substitution of experimental forms with unique and innovative aesthetic works. In 1991 he gave a course on Inism at the University of Paris XII - Val de Marne (France). In 1992 an important biannual poetry award was founded in Spain (Collado-Villalba - Madrid) bearing his name ("Premio Inista de Poesía "Gabrielle-Aldo Bertozzi""). October 1994 saw the second year of this ceremony.

Bertozzi has made important rediscoveries, among whom Lacenaire, Charles Cros, Nicolas Beauduin, but only a few of his most important studies will be remembered here: Saggio sull'avanguardia, Roma, Edizioni dell'Ateneo, coll. "Nuovi Saggi", 1989, Rimbaud. Vita amore e poesia da reinventare, Roma, Lucarini, coll. "Proposte", 1990 (essays) and La Signora Proteo, Padova, Piovan, 1990 (theatrical work in three acts now republished in Edizioni Scientifiche Italiane); Rimbaud. Le opere, i luoghi, Chieti, Métis, coll. "Init", 1991; Inismo Spagnolo e Argentino, Chieti, Solfanelli, coll. "Plaisance", 1992 (Anthology); Forward, translation and notes to Illuminazioni and Una Stagione all'inferno by A. Rimbaud both volumes published for the TEN series, Newton Compton Editori, the first in 1994 and the second in 1995. At the moment there is also in the press an introduction and translation for "Oscar" Mondadori of A. Rimbaud's Viaggio nell'Harrar e nell'Ogladine. He is also preparing a volume entitled Dall'alchemia al multimediale. Saggio sull'Inismo.

He has been head of the Literature and Languages Department at the "G. d'Annunzio" University (1993-1997).

A researcher in French language and literature at the "G. d'Annunzio" University in Pescara, he has published a book of comparative literature Di qua e di là dall'immagine. Letteratura e cinema nelle avanguardie francesi del Primo Novecento, Chieti, Solfanelli, 1992 and has become a part of the editing staff of Bérénice. As Bertozzi has affirmed, "from his writing emerges those reference points and preferences that characterise his development in the French avant-garde scene and in which is revealed a particular predilection for Desnos and Surrealism, which, in his turning from research to creativity prefigured his entrance into the INI movement with unexpectedly original results. In 1988 he made the film entitled ini 96S and in June of the same year took part with other inists in the Salon Comparaison at the Grand Palais in Paris"5. He is the co-signatory of the manifesto Videoinipoesia (Rome, 17 June 1990) and the producer of the first videoinipoesia Telefonata a Rimbaud (Sant'Apollinare 16 September 1990) presented in Paris during the course on Inism held by G-A. Bertozzi at the University of Paris XII- Val de Marne (January 1991). It is with him that the multimedial forms and inist cinema took a definite turning point. We may recall here his film De Rimbaud a Bertozzi, Ini soit qui mal y pense. He is also an active member of C.U.S.M.A.R.C. (University Centre of Applied Multimedial Development for the Research and study of Creativity). During the International avant-garde Conference "Di quà e di là dalla parola. La Lettera e il Segno nelle "Scritture" Contemporanee" he read a paper entitled L'Inisme et les mondes virtuels, which was later published in Bérénice, (March 1993). His creativity and professionalism are most apparent also in his odeporic works Au pays des poétes maudits 6 and Essence absolues, published in Bérénice, II 5 (July 1994). He took part in "INIb(a)m(a)bINI. Incontro con l'infanzia" courses7 with his contribution Il mondo delle immagini. Starting from the computerised graphic elaboration of a single image he has indicated a way of making films as part of a creative inist project applicable to children's forms of expression with the aid of videoclips and films already made within the inist circle. He is president of the ASSO Cultural Association (Arte Scienza e Senso Olistico) which has two journals, "Lintsella" devoted to Inism and "Arcipelago" devoted to critical studies.
