novelist who imparted new vigour to Christian fiction in Switzerland.

Federer started to write when asthma, from which he suffered all his life, put an end to his work as a priest in 1899. He then worked as a journalist in Zürich and after 1907 as an independent writer. He had been raised in the Roman Catholic tradition among peasants and mountains of the Sarner region, and these themes remained, with local variations, predominant in his books. His warmhearted Roman Catholicism was derived from his greatest inspiration, St. Francis of Assisi, whose country he often visited.

Federer's wide reading kept his realistic art free from the nationalistic outlook of the Heimatkunst (“Homeland Art”) movement, which took Swiss and German rural life as its subject in novels and literary sketches. His novels include Der heilige Franz von Assisi (1908; “Saint Francis of Assisi”), Lachweiler Geschichten (1911; “Lachweil Stories”), Berge und Menschen (1911; “Mountains and Men”), Sisto e Sesto (1913; “Sixtus and Sesto”), Umbrische Reisegeschichtlein (1921; “Umbrian Travel Stories”), Papst und Kaiser im Dorfe (1925; “Pope and Emperor in the Village”), and the autobiographical work Am Fenster (1927; “On the Window”). His complete works were published in 12 volumes (1931–38).
