Richard Jezak and Harold Butler
founded Denny's as Danny's Donuts in Lakewood, California in 1953.
It expanded to twenty restaurants by 1959, when the chain was
renamed Denny's to avoid confusion with another chain, Coffee
Dan's.
KKR bought 47% of Denny's among others from owner TW corporation.
Eventually, Denny's operations dominated the parent company so
much that the Flagstar Companies changed its name to Denny's
Corporation.
