Phi Beta Sigma Fraternity, Inc. celebrates its annual Founders Day as one of the oldest and largest African-American fraternities. For 108 years, the men of Phi Beta Sigma have stood by the fraternity's motto, "Culture for service and service for humanity."

Over a century after its founding by three Howard University students —  Leonard Frances Morse, Abram Langston Taylor, and Charles Ignatius Brown — Phi Beta Sigma continues to thrive on its founders' original ideals of Brotherhood, scholarship, and service.

The fraternity has brought together brothers of all backgrounds, during its 109-year existence, dedicated to making the world a better place. Among them are former presidents, athletes, businessmen, and entertainers. Phi Beta Sigma holds more than 200,000 members in over 700 chapters throughout the United States, Europe, Asia, and the Caribbean. Here are some of the most notable members of the fraternity:
