Eugenio Gerli (Milan, 1923 – 2013) opened his firm in 1949 and began experimenting with new materials such as plastic felt and curved plywood. 1957 marked the start of a long and extraordinary partnership with Osvaldo and Fulgenzio Borsani and Techno, for whom he designed the historic operating system Graphic (1968) and other icons such as the PS142 and S142 seats. In the 1970s, he was joined in the business by his sons Enrico and Guido, who now also manage the Archive.
