Josef Müller-Brockmann was a Swiss graphic designer and teacher, mostly recognised for his simple designs and his clean use of typography, notably Helvetica. His shapes and colours have inspired many graphic designers in the 21st century, and made him one of the main precursors of the International Typographic Style, also known as Swiss Style. This visualization is the result of a personal web research about Josef Müller-Brockmann and the international typographical style. It contains 3 key elements: (1) the research of information on the web, (2) chronological information on Josef Muller-Brockmann's life and links to the last part, and finally the last part (3) is composed of a critical article based on information found online. The project is in french.
