Ivan Chermayeff, designer of familiar logos, dies at 85

Ivan Chermayeff, a graphic designer who forged some of the most recognizable corporate logos of the second half of the 20th century — including those of the cable channel Showtime, the publisher HarperCollins, the Smithsonian Institution and Pan Am — died Saturday at his home in Manhattan. He was 85.

His family confirmed the death.

Esteemed as one of the foremost graphic artists of his era, Chermayeff was at his death a partner of the New York design concern now known as Chermayeff & Geismar & Haviv, which he founded in 1957 with Tom Geismar and Robert Brownjohn.
