Léo Campion

Léo Campion (born Léon Louis Octave Campion; 24 March 1905 in Paris – 6 March 1992 in Paris) was a French actor and active freemason. Léo Campion's father was Belgian and his mother French (from Montmartre, Belgian at birth).

In 1923, Léo Campion was expelled from France following a campaign waged against him by Action Française: he still held Belgian nationality.

He settled in Brussels, where he met the anarchist bookseller and freemason Marcel Dieu, alias Hem Day. It was a meeting that marked his life.

He became secretary of the Brussels Libre Pensée and secretary of the Belgian section of the War Resistance International (IRG-WRI).
