Which chain of hotels was founded by Kemmons Wilson in 1952?

Charles Kemmons Wilson (January 5, 1913 – February 12, 2003) was the founder of the Holiday Inn chain of hotels. Holiday Inn is a British-owned American brand of hotels, and a subsidiary of InterContinental Hotels Group. Founded as a U.S. motel chain, it has grown to be one of the world's largest hotel chains, with 1,145 active hotels as of September 30, 2016. The hotel chain's headquarters are in Denham, Buckinghamshire.

Wilson initially came up with the idea after a family road trip to Washington, D.C., during which he was disappointed by the quality of the roadside hotels of that era. The name Holiday Inn was given to the original hotel by his architect Eddie Bluestein as a joke, in reference to the 1942 movie of the same name.

He opened the first Holiday Inn motel in Memphis in 1952, and quickly added others to create an entire hotel chain. Holiday Inn went international in 1960. Wilson and his financial partner Wallace E. Johnson (1901-1988) were practicing Christians who saw to the placing of a Bible in every one of their hotel rooms and who donated much of their growing fortunes to charitable enterprises.
