Gary Anderson (right): creator of the recycling symbol
1970 

Anderson was a 23-year-old USC Architecture graduate when he entered the Container Corporation of America’s design contest to create what would become the universal symbol for recycling. From Wikipedia: The 500 entries to the competition were judged by designers recognized as world leaders in graphics and industrial art, including Saul Bass, Herbert Bayer, James Miho, Herbert Pinzke and Eliot Noyes. According to Anderson: “Angela Davis had just shot up the courthouse and the Manson murders had just happened. I wanted to move away from that, from the Haight-Ashbury poster art with its amorphous organic shapes to create something simpler and cleaner.”
