Branche participated in the
Cambridge Movement in
Dorchester County, Maryland, as the field secretary for the NAACP. He was one of the signatories of "The Treaty of Cambridge" which initiated desegregation in the city. He returned to Chester in 1962 and his wife Anna introduced him to
George Raymond, president of the Chester branch of the NAACP. Branche was initially assigned to the campaign to desegregate the Great Leopard Skating Rink. Branche and Raymond partnered to successfully challenge the minority hiring practices of large department stores, clothing shops, shoe stores and other specialty shops in downtown Chester. By the fall of 1963, Branche became frustrated with the gradualist approach of Raymond and the NAACP. He resigned and created a new activist organization named the
Committee for Freedom Now (CFFN) along with the
Swarthmore College chapter of
Students for a Democratic Society and Chester parents to end de facto segregation of public schools and improve conditions at predominantly black schools in Chester. In 1962, Branche and the CFFN focused on improving conditions at the predominantly black Franklin Elementary school in Chester. Although the school was built to house 500 students, it had become overcrowded with 1,200 students. The school's average class-size was 39, twice the number of nearby all-white schools. The school was built in 1910 and had never been updated. Only two bathrooms were available for the entire school. In the spring of 1964, huge protests over multiple days ensued which resulted in mass arrests of protesters. The mayor of Chester,
James Gorbey, issued "The Police Position to Preserve the Public Peace", a ten-point statement promising an immediate return to law and order. The city deputized firemen and trash collectors to help handle demonstrators. The State of Pennsylvania deployed 50 state troopers to assist the 77-member Chester police force. Over six hundred people were arrested over a two-month period of civil rights rallies, marches, pickets, boycotts and sit-ins. Branche acted as press spokesman, community liaison, recruiter and chief negotiator. Governor
William Scranton convinced Branche to obey a court-ordered moratorium on demonstrations. Scranton created the Pennsylvania Human Relations Commission to conduct hearings on the de facto segregation of public schools. All protests were discontinued while the commission held hearings during the summer of 1964. In November 1964, the Pennsylvania Human Relations Commission concluded that the Chester School Board had violated the law and ordered Chester School District to desegregate the city's six predominantly African-American schools. The city appealed the ruling, which delayed implementation. ==Post civil rights career==
