Yup, Salvador Dalí is probably the most famous.
Other Surrealists were dedicated to revolution and kind of outcasted Dalí because he was apolitical.
Rene Magritte is perhaps the second most famous, and my personal favorite Surrealist.
The 'head' of Surrealism was Andre Breton.
Other famous Surrealists include Max Ernst, Yves Tanguy and Giorgio de Chirico.
