Gerald Cinamon was born in Boston in 1930, and while at Yale University's Department of Graphic Arts in its School of Art and Architecture, he studied under some big names including Paul Rand, Herbert Matter, Alvin Eisenman and Armin Hofmann. He moved to England in 1960. In 1965 he joined Penguin Books and spent 20 years there, eventually becoming chief designer. Influenced by Swiss design, Cinamon works were a combination of bold colours, clean lines and sans serif typography that look as modern and fresh today as when they were first created.
