superintendent, was convicted of the murder of a 13-year-old girl in a highly publicized trial. He was sentenced to death but the governor commuted his sentence to life. An enraged and organized lynch mob took him from jail in 1915 and hanged him in Marietta. The Jewish community in Atlanta and across the country were horrified. On May 21, 1917, the Great Atlanta Fire destroyed 1,938 buildings in what is now the Old Fourth Ward, resulting in one fatality and the displacement of 10,000 people. On December 15, 1939, Atlanta hosted the premiere of Gone with the Wind, the epic film based on the best-selling novel by Atlanta's Margaret Mitchell. The gala event at Loew's Grand Theatre was attended by the film's legendary producer, David O. Selznick, and the film's stars Clark Gable, Vivien Leigh, and Olivia de Havilland, but Oscar winner Hattie McDaniel, an African-American actress, was barred from the event due to racial segregation laws. Metropolitan area's growth Atlanta played a vital role in the Allied effort during World War II due to the city's war-related manufacturing companies, railroad network and military bases. The defense industries attracted thousands of new residents and generated revenues, resulting in rapid population and economic growth. In the 1950s, the city's newly constructed highway system, supported by federal subsidies, allowed middle class Atlantans the ability to relocate to the suburbs. As a result, the city began to make up an ever-smaller proportion of the metropolitan area's population. Georgia Tech's president Blake R. Van Leer played an important role with a goal of making Atlanta the home of the "MIT of the South." In 1946 Georgia Tech secured about $240,000 () annually in sponsored research and purchased an electron microscope for $13,000 (), the first such instrument in the Southeastern United States and one of few in the United States at the time. The Research Building was expanded, and a $300,000 () Westinghouse A-C network calculator was given to Georgia Tech by Georgia Power in 1947. In 1953, Van Leer assisted with helping Lockheed establish a research and development and production line in Marietta. Later in 1955 he helped set up a committee to assist with establishing a nuclear research facility, which would later become the Neely Nuclear Research Center. Van Leer also co-founded Southern Polytechnic State University now absorbed by and made part of Kennesaw State University to help meet the need for
