Harvey Ball
Harvey Ross Ball was an American commercial artist. He is recognized as the inventor of the popular smiley face graphic picture, which became an enduring and notable international icon. He never applied for a trademark for the iconic smiley image and only earned $45 for his efforts.

Smiley
A smiley, sometimes called a smiley face, is a basic ideogram representing a smiling face. Since the 1950s, it has become part of popular culture worldwide, used either as a standalone ideogram or as a form of communication, such as emoticons. The smiley began as two dots and a line representing eyes and a mouth. More elaborate designs in the 1950s emerged, with noses, eyebrows, and outlines. New York radio station WMCA used a yellow and black design for its "Good Guys" campaign in the early 1960s. More yellow-and-black designs appeared in the 1960s and 1970s, including works by Harvey Ross Ball in 1963, and Franklin Loufrani in 1971. Today, The Smiley Company founded by Franklin Loufrani claims to hold the rights to the smiley face in over 100 countries. It has become one of the top 100 licensing companies globally.
