From Wikipedia: "Fred Anderson (March 22, 1929 – June 24, 2010) was an American jazz tenor saxophonist who was based in Chicago, Illinois. Anderson's playing was rooted in the swing music and hard bop idioms, but also incorporated innovations from free jazz, rendering him, as critics Ron Wynn and Joslyn Layne have written, "a seminal figure among Chicago musicians in the '60s."
