RayKroc opened the world's first McDonald's restaurant in Desplance, Illinois on April 1955. The opening of this restaurant marks the birth of McDonald's brand and the beginning of Rick Locke becoming the father of McDonald's.
Rick Locke discovered McDonald's Brothers Restaurant at 1954. At that time, the restaurant had opened 10 chain stores in San Bernardino town in the western United States.
After three days' observation, Rocklake found that the management direction of McDonald's was in line with the pace of American life and had broad market prospects, so he proposed to McDonald's brothers to promote McDonald's chain stores throughout the country.
