Ernst Fuchs was an Austrian painter, draftsman, printmaker, sculptor, architect, stage designer, composer, poet, and one of the founders of the Vienna School of Fantastic Realism. In 1972, he acquired the derelict Otto Wagner Villa in Hütteldorf, which he restored and transformed. The villa was inaugurated as the Ernst Fuchs Museum in 1988.

Tempera, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint.
