With René de Weck and Léon Savary, he formed the troika of Fribourg writers of the early twentieth century.
A member of the minor Fribourgeois nobility, de Reynold was born at his family's sixteenth-century chateau in Cressier.
[2] Consistently "sceptical of liberal democracy and scathing about modernity in all its forms", de Reynold devoted his life to the promotion of Swiss nationalist and right-wing, traditionalist Catholic causes.
[3][4] In letters, he described longtime Portuguese dictator António de Oliveira Salazar as a friend[5] and paid a personal visit to Benito Mussolini in 1933.
He served as the Swiss delegate to and rapporteur of the International Committee on Intellectual Cooperation, a body of the League of Nations and precursor to UNESCO, from its inception in 1922 to its demise in 1939.
