Jonathan (or in Italian Gionatan) De Pas studied at the Politechno di Milano where he met Donato D’Urbino and Paolo Lomazzi with whom he in 1966 established the DDL Studio. In 1967 the trio together with Carla Scolari made a great success with Blow, the first mass-produced inflatable armchair made of PVC by Zanotta.
Blow is seen as a symbolic object of the 1960’s that questioned the shape of furniture design. In 1972 the studio also designed several inflatable structures for the World’s Fair in Osaka, Japan. Three years after Blow was released D’Urbino, de Pas and Lomazzi launched the leather baseball glove shaped lounge chair Joe, named legendary player Joe DiMaggio and made by Poltrovna.
During the 1970’s and 80’s the design studio concentrated on furniture that were more traditional and made of wood, steel, and leather, such as the chair Linda in 1975 and Onda in 1985 both made by Zanotta. They also designed furniture for BBB Bonacina, Driade and Palina as well as lighting for Stilnovo.
Jonathan De Pas passed away in 1991 at the age of 59.
