Most of the texts have been taken from Emmanuelle Foster’s book Ferdinand Springer (Editions Ides et Calendes, 1995). Other texts were written by Francis Ponge, Alain Paire and Martine Lusardy.

The photographs of Ferdinand Springer and his surroundings were taken by André Villers, Willy Maywald, Alain Sabatier and Alkis Voliotis.

Hortense v. Heppe provided valuable advice.

The translation of the texts in English was supervised by Lyn Tuit.
