‘How is Pauli Murray not a household name?’ The extraordinary life of the US’s most radical activist

She explored her gender and sexuality in the 20s, defied segregation in the 40s and inspired Ruth Bader Ginsburg. Now, a film is bringing her trailblazing achievements to light

It seems inconceivable that someone like Pauli Murray could have slipped through the cracks of US history. A lawyer, activist, scholar, poet and priest, Murray led a trailblazing life that altered the course of history. She was at the forefront of the battles for racial and gender equality, but often so far out in front that her contributions went unrecognised.

In 1940, 15 years before Rosa Parks, Murray was jailed for refusing to move to the back of a bus in the Jim Crow south. In 1943, she campaigned successfully to desegregate her local diner, 17 years before the Greensboro lunch counter sit-ins of 1960. Her work paved the way for the landmark supreme court ruling Brown v Board of Education in 1954 - which de-segregated US schools - to the extent that Thurgood Marshall, a lawyer for the NAACP civil rights group, called Murray's book States' Laws on Race and Color the bible for civil rights lawyers".
