Rosmarie Tissi grew up in an artistic family in Tayngen in the canton of Schaffhausen. She completed her apprenticeship as a graphic designer with Siegfried Odermatt in Zurich. After working together for ten years, she and her mentor set up the collective studio O&T in 1968. Their clients include printing houses, companies of all kinds, cultural institutions and the public sector. Her designs are characterised by an objectively clear yet undogmatic style, and the approach whereby writing influences form can be called a style-defining characteristic of Tissi’s work. However, she has always steered clear of straight-laced ‘Swiss style’. The graphic designer is also known for her love of travelling, which has already taken her to over 60 countries – not just for pleasure, mostly for lectures and workshops in high-profile institutes and universities on all five continents.
