Aguigui Mouna, whose real name was André Dupont, was born on October 1, 1911, in Meythet, Haute-Savoie, into a modest family marked by odd jobs and precarious employment. Early on, he rejected authority after a brief stint in the Navy and his expulsion from the Communist Party, which led him down a personal path blending pacifism, a libertarian spirit, and a biting sense of humor.

In the 1950s, after several professional setbacks on the French Riviera and in Paris, he "invented" the character of Aguigui Mouna, a libertarian, philosophical tramp who decided to make the street his stage. Based primarily in Paris, he became a familiar figure in the Latin Quarter and the Beaubourg district, riding a brightly colored bicycle, his half-beard and half-mustache serving as a permanent manifesto. He harangues passersby against war, militarism, nuclear power, and consumer society, wielding slogans, puns, and aphorisms at the crossroads of humor and meditation.

Mouna is involved in numerous causes: conscientious objection, the anti-nuclear movement, refugee advocacy, denunciation of child labor, and radical critique of productivism. He disseminates his ideas in a small newspaper, Le Mouna Frères, which expresses a pioneering environmentalism, a cheerful humanism, and non-violent anarchism. In May 1968, his constant presence in the streets, his verve, and his whimsical nature make him an emblematic figure of a joyful, poetic, and anti-authoritarian protest.

From the 1970s onward, he runs in several elections—notably the 1974 presidential election—as a "non-candidate," subverting the electoral ritual with deliberately poetic and absurd platforms. He advocated for more bicycles, fewer cars, more green spaces, and fewer weapons, garnering a few thousand votes, primarily in a Parisian constituency in the late 1980s. In a final paradox, he was awarded the title of Knight of the Order of Arts and Letters, an official recognition of a subversive jester who relentlessly challenged those in power.

Until the end of his life, he continued to roam Paris, engaging in impromptu interventions, sidewalk conversations, and pacifist provocations, remaining true to a philosophy that blended derision and gravity. Aguigui Mouna died on May 8, 1999, at Bichat Hospital in Paris, leaving behind the image of a "public entertainer" and a wise outsider, the embodiment of a poetic, ecological, and non-violent anarchism in the heart of the modern city.
