The only son was seen as the successor of his father, and therefore he was sent from 1940 to 1942 to the monastery school at the Engelberg Abbey, that he called a restricted area exclusively for men, but he abandoned.

Authors such as Alfred Andersch, Peter Bichsel, Helmut Heissenbüttel, Alexander Kluge, Kurt Marti, and Jörg Steiner were published, but not Otto F. Walter himself.

Walter's progressive program found little support by the conservative company itself, nor by his Catholic family, despite the balance sheet.

In 1959 Walter's first novel "Der Stumme" (literally: The Silent) found the attention of a wide readership, published in the Kösel Verlag München, as well as three years later the novel "Mr. Tourel", and again three years afterwards appeared the theater play "Elio oder Eine fröhliche Gesellschaft" (literally: Elio or a happy society).

Ascended to the head of the publishing house, Walter left München in 1973, and returned again to Switzerland, first to Oberbipp and later to Solothurn, to turn increasingly to write.

His novels distinguished themselves through their passionate presence in cover and their current theme, and appeared at regular intervals at the then Rowohlt publishing house.

[2][4] In 1993, a further novel was published, "Die verlorene Geschichte", a passionate portrait of a xenophobe, the last testimony of Otto F. Walter's literary contemporariness.
