This week's feature looks at St. Louis nightlife and those who helped shape it. No discussion of St. Louis' social scene would be complete without mentioning Gaslight Square of the 1950s and '60s, centered on what's now Boyle and Olive streets in the Central West End. Artists, musicians and patrons flocked to the vibrant entertainment district, which was home to jazz clubs, cabarets, restaurants and more. The State Historical Society has literally thousands of Gaslight Square photos -- here are 27 we especially love. All photos courtesy of the State Historical Society of Missouri.
