Eusebio Sempere was born in Onil, Alicante on 3 April 1923. Painter, sculptor and graphic artist who began his studies at the Academy of Fine Arts of San Carlos de Valencia.
In 1948 he moved to Paris with a scholarship to continue his studies. There he establishes contact with avant-garde artists such as Chillida, Kandinsky, Mondrian, Picasso, Matisse and Klee. In Paris his work is influenced decisively by these artists and perfects his technique in fine arts, especially in the silkscreen, that he frequently uses during the subsequent years.
From this moment, his work is characterized by abstract and geometric constructions and the study of light in the visual arts. This trend is seen in the two works with which he participates in 1956 at the Salon des Réalités Nouvelles de Paris.
In 1960 he moved to Madrid where he contacts the informalism through "Grupo de Cuenca". Also takes part in the "Grupo Parpalló" in Valencia.
In 1964, Sempere has an exhibition in the Bertha Schaefer Gallery in New York and participates in the Pavilion of the New York State Fair.
Four years later Sempere participates in a seminar about "Automatic generation of plastic forms" at the Calculus Center of the University City of Madrid. At this seminar he focused on creating sculptural forms by using computers. In 1969 he travels to America where he composes his artistic creations using computers. On his return to Spain he keeps studying this technique, becoming a pioneer of this new form of artistic creation.
In 1983 he was awarded with the Prince of Asturias Arts Award. He was appointed favorite son of the city of Alicante. He died in April 1985 in his hometown following a long illness.
