Jean Arp - also known as Hans Arp - is best known as an abstract artist, both in painting and sculpture, but his career touched on many other styles. He was influenced by the Blaue Reiter school of artists such as Kandinsky before helping to found the Dadaist art movement. He was involved with the art of many of the earlysurrealists, such as Max Ernst, and exhibited at surrealist shows in the mid to late 1920s, but split from the surrealists in about 1931.
Arp's surrealist-influenced paintings are considerably more abstract than many of the works of other well-known surrealists - it's certainly more in the realm of "organic surrealism" (amorphous and non-representational) than the more recognisable forms of "narrative" symbolism, and is therefore more in line with the surrealist art of Miro and Tanguy than Dali and Magritte. It's often the titles which give a clue to the more surrealist element, as in "The Elements: Leaf transformed into a torso" and "Moustache hat".
There are a considerable number of Arp's works pictured at http://www.all-art.org/art_20th_century/… several of which would qualify as surrealist
