He also founded and edited the literary reviews Livre d'Art with Alfred Jarry and Vers et Prose (1905–14) with poet Guillaume Apollinaire, which published the work of Paul Valéry and other important Symbolist writers.

At 17, Fort frequented the Left Bank hangout of the Symbolist poets, the Café Voltaire (1, Place de l'Odéon), where the discussion included contemporary theatre.

These inaugural works included not only efforts by Fort and Germain but also Marc Legrand, le Sr de Chanmêlé, Charles Grandmougin, and Joseph Gayda.

But an important discovery also debuted in the second program: Georgette Camée (d. 1957), a Paris Conservatory student, who became a seminal actor in the nascent avant-garde theatre movement, and would appear in 22 plays with the Théâtre d'Art.

She eventually married writer Maurice Pottecher and joined him in his own regional theatre endeavor, the Théâtre du Peuple, in Bussang, France.

For the next two years, he moved regularly between acting for the Théâtre d'Art and directing for the amateur company Le Cercle des Escholiers.

He, along with Georgette Camée, forged the signature Symbolist acting style that conveys a religious reverie, with its hieratic poses and gestures, matched with solemn, psalmodized line readings.

[10] As an artistic director, however, he proved himself ambitious but in over his head; he was often over budget, unable to deal with his creditors, and straining technically to produce difficult, opaque dramatic material.

[11] By 1892, with the Parisian critics begging him to make better choices, Fort sought in vain to produce Villiers de L'Isle-Adam's Axël as the way to reinstate the company's reputation.

In 1905, he began publishing the magazine Vers et prose with Moréas and Salmon, who notably edited the works Guillaume Apollinaire, Max Jacob, Pierre Louÿs.

Fort lead the ceremonies, Severini had as witnesses Guillaume Apollinaire, and Filippo Marinetti, the author of the Futurist Manifesto.

His work was banned by the CNE (National Writers' Committee of the intellectual resistance) at the end of war, but the interdiction was rescinded in a second list published in the Les Lettres françaises of 21 October 1944.

Fort is mentioned by Ernest Hemingway as a customer of La Closerie des Lilas [fr], in A Moveable Feast.
