What is the name of KFC's mascot and founder, commonly shown in a white suit?

KFC's white-suited mascot and founder is Colonel Sanders.

Colonel Harland Sanders developed the fried-chicken recipe associated with Kentucky Fried Chicken and became the company's public face. His carefully groomed white hair, goatee, black string tie, and white suit formed one of the most recognizable restaurant portraits in the world.

“Colonel” was an honorary Kentucky title rather than a military rank. Kentucky governors awarded the title to people who contributed to the state, and Sanders used it as part of his public identity.

Sanders began selling fried chicken from a roadside restaurant in Corbin, Kentucky, before building a franchising business. KFC later became a global chain, while his image remained central to its branding.
