Otl Aicher (1922–1991) was a visionary German graphic designer and typographer, best known for his clean, modernist aesthetic and his iconic design work for the 1972 Munich Olympics. Born in Ulm, he grew up under the oppressive climate of Nazi Germany and was arrested for refusing to join the Hitler Youth. After World War II, Aicher co-founded the influential Ulm School of Design (Hochschule für Gestaltung Ulm) in 1953, which became a hub for modernist design thinking. His most notable work is the design system for the 1972 Olympics, which included a universally recognised set of pictograms, vibrant colour schemes, and a sleek sans-serif typeface, setting a new standard for event branding. Aicher also created branding for major companies, including Lufthansa and Braun, and authored books on design theory. His approach emphasised functionality, clarity, and cultural relevance, leaving an enduring impact on the world of design.
