On March 4, 1968, a crowd of high school and university students were gathered at the Omaha Civic Auditorium to protest the presidential campaign of George Wallace, the segregationist governor of Alabama. After counter-protesters began acting violently toward the youth activists, police brutality led to the injury of dozens of protesters. An African-American youth was shot and killed by a police officer during the melee, and fleeing students caused thousands of dollars of damage to businesses and cars. The following day a local barber named Ernie Chambers helped calm a disturbance and prevent a riot by students at Horace Mann Junior High School. Chambers was already recognized as a community leader. After finishing his law degree, Chambers was elected to the Nebraska State Legislature, and served a total of 38 years, longer than any of his predecessors. African-American teenager Vivian Strong was shot and killed by police officers in an incident at the Logan Fontenelle Housing Projects on June 24, 1969. Young African Americans in the area rioted in response to the teenager's death, with looting along the North 24th Street business corridor. During this initial surge, eight businesses were destroyed by firebombing or looting. Rioting went on for several more days. This is the last noted riot in Omaha. The effects of these riots is still evident in the North 24th Street district, with high numbers of vacant lots and general economic depression still prevalent. Commemorations and recognitions There have been several different organizations formed to commemorate the history of Omaha's African Americans. In the 1960s Bertha Calloway founded the Nebraska Negro Historical Society, and in 1974 the Society opened the Great Plains Black History Museum. It includes material related to the history of black homesteaders on the plains, as well as the more numerous urbanites based chiefly in Omaha, the major city of the state. In 1976 the community began Native Omaha Days, devised as a series of activities to celebrate black history in the city. In addition to being a labor organizer in meatpacking in the 1940s, Rowena Moore led an effort to recognize the Malcolm X House Site in the 1970s. A monument to Dr. Martin Luther King Jr. was placed along North 24th Street in the late 1990s. The Omaha Black Music Hall of Fame was founded in 2005 to celebrate the city's musical history.
