‘Together with Inge Scholl, sister of Hans and Sophie Scholl, who were executed in 1943 as members of the “Weie Rose” resistance group, Otl Aicher designed the Ulm Adult Education Center, which opened on April 24, 1946. Soon after, Aicher began designing their image with special posters. For the ideologically influential core events, which became known as “Thursday Lectures”, he created upright format posters and square posters for the courses. The content is converted into visual communication through shapes, colours and letters. Aicher’s posters up until 1960, when he passed this part of his work on to others, show which of these design elements were used and in what way. For example, your own typeface designs are replaced by typographic design and figurative elements by abstract geometric shapes. The book shows how shapes and colours are used to encode specific content, and as such is a small but useful grammar of graphic poster design. The author, who accompanied Aicher’s development for some time, first as a student, then as an employee and co-author, shares insights and experiences from the creative process of the posters. He compiled, dated and explained Aicher’s posters for the Ulm adult education centre as completely as possible. He names the influences that have shaped the work of Otl Aicher and passes on insights into the understanding of the effect and composition of the posters.’
