Erik Nitsche: The Reluctant Modernist
by Steven Heller
Eric Nitsche may not be as well known today as his contemporaries, Lester Beall, Paul Rand, or Saul Bass, but he is their equal. Almost 90 years old, this Swiss born graphic designer is arguably one of the last surviving Modern design pioneers. Although he never claimed to be either a progenitor or follower of any dogma, philosophy, or style other than his own intuition, the work that earned him induction last year into the New York Art Director’s Club Hall of Fame, including the total identity for General Dynamics Corporation from 1955 to 1965 and the series of scientific, music, and world history illustrated books, which he designed and packaged during the 1960s and 1970s, fits squarely into the Modernist tradition.
