Forrest Gump didn’t create the smiley face. Harvey Ross Ball gets credit for that moment of genius. An artist and ad guy, Ball was commissioned in 1963 to create a graphic to help raise morale for employees of an insurance company that had been through a few tough mergers and acquisitions.

The goal? Get the employees to cheer up and smile more. Just 10 minutes of brilliance and $45 later, the iconic black-and-yellow smiley face was born.

The Science Behind The Smile

Ball’s art has science on its side. Smiling and laughing release endorphins, “feel-good” chemicals that boost happiness and relieve stress and pain. Bonus: When you smile, you activate the joy region of the brain in a cool feedback loop—you either smile and are joyful, or are joyful and then smile.

“Smile” is the ninth and final factor of the H.A.P.P.I.N.E.S.S. equation. It’s the last in a nine blog series on Forbes taking a closer look at all of the factors that help businesses increase happiness to drive growth, productivity and bottom-line results.
