As graphic design has evolved over the course of the twentieth century and into the twenty-first century from a craft focusing on the finer aspects of printing and typesetting into a multifaceted profession thriving on the communication of messages through a variety of means and mediums, there have been numerous individuals, and groups of individuals, that have helped not only define each milestone but propel the next one forward through outstanding and innovative work upon which future generations can build upon. These individuals are representative of a specific time in the history of graphic design, but at the same time transcend any given period or style by being exemplary models for how graphic design can be practiced and of the kind of work that can be produced within any cultural, political, economical and technological context.
