Philippe Sollers was a French writer and critic. In 1960 he founded the avant garde literary journal Tel Quel, which was published by Le Seuil and ran until 1982. Sollers then created the journal L'Infini, published first by Denoel, then by Gallimard with Sollers remaining as sole editor.

Éditions du Seuil, also known as Le Seuil, is a French publishing house established in 1935 by Catholic intellectual Jean Plaquevent (1901–1965), and currently owned by La Martinière Groupe. It owes its name to this goal "The seuil (threshold) is the whole excitement of parting and arriving. It is also the brand new threshold that we refashion at the door of the Church to allow entry to many whose foot gropes around it".
