Oswald Wirth, born August 5, 1860 in Brienz, Switzerland and died March 9, 1943 in Mouterre-sur-Blourde, France was the secretary of Stanislas de Guaita, and drew in collaboration with him a Tarot of  22 Major Arcana (1889), republished since under the name of Tarot of Wirth. This Tarot is explained and commented on in his book (1926/27) Le Tarot des Imagiers du Moyen Age, which has become a classic.
