William Henry Jernagin was a devout Christian and fierce advocate for civil rights in the first half of the twentieth century. He was senior pastor of the Mount Carmel Baptist Church in the Mount Vernon Square neighborhood for more than forty-five years. His activism made him an internationally recognized figure. He was a foundational leader in the American civil rights movement. His residency allowed him to contribute to the collective action to abolish Jim Crow in the nation's capital. Through his office in the National Baptist Convention, he also identified the potential in a lesser-known leader of the time, Martin Luther King Jr. Jernagin's passion lifted him to leading positions in the National Baptist Convention and National Fraternal Council of Negro Churches, as well as close work with Presidents Roosevelt, Truman and Eisenhower. Author Ida E. Jones reveals the story of this often-overlooked leader and his fight for civil rights while living in the District of Columbia.
