Marco Gaudenzi was born in Pesaro in 1949. He graduated in architecture from the University of Rome in 1976, with a thesis entitled: ‘A residential complex for the elderly in Pesaro’. Since 1976, he has created some 150 design projects for all areas of civil and industrial building, including the building of an experimental theatre in Pontedera. Since 1987, he has been the creator and art director of Tonelli, together with the owner of the company, Massimo Bellazecca, bringing in designers such as Isao Hosoe, De Pas, D’Urbino, Lomazzi and Luigi Serafini. In the design field, he works on occasional, non-specific projects that have seen him collaborate with Tonelli in the furniture industry, MFFM in the jewellery sector, and Benelli for hunting rifles. As part of an overall research project into mobility, which he carried out in conjunction with Isao Hosoe, he created ‘Fluida’, a ‘bag’ bicycle.
