On August 19, 1958, the NAACP Youth Council occupied the counter of Katz Drug Store in Oklahoma City. The youth council was accompanied by Clara Luper, who was an educator and the director of the NAACP Oklahoma City Youth Council. Luper knew the drugstore was segregated but, she still asked to be served. They were denied and then returned the next day. Two days after the sit-in, Katz corporate management desegregated its lunch counters in Oklahoma, Missouri, and Kansas.
