Born Guido Hess on 10 October 1909 in Turin, he belonged to a Jewish family of Egyptian origin which had settled in Liguria.

It is linked to his love for the sea and for the city which he considered his true hometown: Bordighera, a constant point of reference in his many trips abroad.

His lived at Via Pelloux 44[2] Bordighera and its hinterland are the background of Seborga's literary works; the Vallée des Merveilles and the Ligurian Sea are the references of his art.

[5] Antifascist groups in Turin led him to join the Italian resistance, first with the Action Party along with Giorgio Agosti, Alessandro Galante Garrone, Ada Gobetti and then as a partisan in the Matteotti Brigades [it].

In Rome with Lelio Basso he directed the magazine Socialismo and he managed the propaganda of the Popular front, which was the union of the leftist parties.

He was among the organizers of the production of the play Woyzeck by Georg Büchner, with Raf Vallone and performed in 1946 for the reopening of the Gobetti Theatre in Turin.

In the 1950s and 60s, Seborga was part of the organization and of the jury of the "Cinque Bettole" award in the categories literature and painting, with the likes of Italo Calvino, Giancarlo Vigorelli, Elio Philip Accrocca, Charles Betocchi and Giuseppe Balbo.

He also contributed to the creation and the development of the Cultural Democratic Union of Bordighera, for which he helped to organize exhibitions, debates, lectures and plays.

For Seborga automation is a danger, namely the risk of bloodshed by the techno-industrial society to which he opposes the moral rigor of Piero Gobetti which refers to civil commitment.

Seborga also approached poetry, his first collection of poems was published in 1965 with the title "Se avessi una canzone", is dominated by the sea, the sun, the wind, rich olive border valleys and vineyards as wild as its inhabitants.
