Aicher spent time fighting in the second world war for the German army, against his own beliefs. The experience affected him greatly and his first contributions as a designer were in an effort to revitalize the public after the devastation of the war. By 1947 Aicher had opened the doors at his own studio, Büro Aicher, and had begun accepting work from a ariety of clients. Together with designer Max Bill he established the Hochschule für Gestaltung in Ulm, Germany and spent many years there as a professor.
Perhaps the most prominent and influential work that he created was the identity system developed for the 1972 Olympics in Munich. The result of several years of work, the graphics were developed on a strict grid system, solely used the typeface Univers and were created from a bright palette developed from the colors of the Bavarian countryside. He was a very proficient typographer and created the Rotis family of typefaces, which include sans-serif, semi-sans, serif and semi-serif iterations. The typefaces were named after the property where he lived and worked from 1972 until his death in 1991.
