Three pioneers of the 1960s civil rights movement will join the U.S. Marshals Museum for Fort Smith's Celebrate the Dream Parade on Martin Luther King Jr. Day next week.

Leona Tate, Tessie Prevost Williams and Gail Etienne Stripling — “The McDonogh 3” — integrated McDonogh No. 19 Elementary School in New Orleans in 1960, six years after the U.S. Supreme Court ruled in the landmark Brown vs. Board of Education case that racial segregation in public schools was unconstitutional.

“The girls, and their families, heavily depended on the help of the marshals to protect them from the hate and hostility of the crowds,” a U.S. Marshals Museum news release states. “In doing so, the marshals upheld the constitutional rights of all citizens to enjoy equal access to society’s benefits.”

Louie McKinney, the first career deputy to lead the U.S. Marshals Service, will also attend the Martin Luther King Jr. Day festivities in Fort Smith on Monday.

McKinney’s career included enforcement of integration in southern public schools. “As a black deputy marshal, McKinney helped us better understand the social instability that defines American history in the late 20th century,” the Marshals Museum release adds.

At 7:30 a.m. Monday, “The McDonogh 3” and McKinney will attend the MLK Celebration Breakfast in the Reynolds Room of the University of Arkansas at Fort Smith’s Smith-Pendergraft Campus Center.

The breakfast will include a panel discussion titled “Love and Unity in the Service of Hope,” which will feature alumni of Fort Smith's Lincoln High School sharing their experiences with integrating into Northside High School.

The group will also take part in the Celebrate the Dream Parade along Garrison Avenue on Monday. The parade starts at 11:30 a.m.

Meet the Pioneers Happy Hour will also be 5:30 p.m. Monday at the Courtyard by Marriott, 900 Rogers Ave. in downtown Fort Smith.

According to the U.S. Marshals Service website, McKinney was appointed by President George W. Bush as the acting director of the Marshals Service in 2001. McKinney became a deputy U.S. marshal in 1968 and served in several leadership capacities including chief inspector for Interpol and deputy chief of Witness Security. Additionally, he was twice appointed by the attorney general to be the U.S. marshal for the Virgin Islands. At the time of his retirement in 1994, he was chief of the Enforcement Division, responsible for numerous fugitive investigations and initiatives.

McKinney’s prior experience also includes seven years in the U.S. Navy, five years as an officer with the Metropolitan Police Department in Washington, D.C., and two years with the Central Intelligence Agency. He has received numerous awards and citations, including several from the attorney general and the White House.
