Emil Ruder was a typographer and graphic designer who, born in Switzerland in 1914, helped Armin Hofmann form the Basel School of Design and establish the style of design known as Swiss Design. He taught that, above all, typography's purpose was to communicate ideas through writing. He placed a heavy importance on sans-serif typefaces and his work is both clear and concise, especially his typography.
Like most designers classified as part of the Swiss Design movement he favored asymmetrical compositions, placing a high importance on the counters of characters and the negative space of compositions. A friend and associate of Hofmann, Frutiger and Müller Brockmann, Ruder played a key role in the development of graphic design in the 1940s and 50s. His style has been emulated by many designers, and his use of grids in design has influenced the development of web design on many levels.
Ruder wrote a book explaining his theories in depth titled Typographie: A Manual for Design.
