Leo Lionni (1910-1999) was a Dutch born artist. During the beginnings of WWII, he left Europe for New York. Without formal training in design, he landed a job at a top advertising agency, N. W. Ayer & Son and became one of America's top art directors. During his professional career at the ad agency he coined the slogan "Never underestimate the power of a woman", used in Ladies Home Journal and pushed for new and exciting imagery commissioning Alexander Calder, Saul Steinberg, Willem de Kooning and the young Andy Warhol. After retiring on his 50th birthday, he moved to Italy to pursue his own creative interests.
