It may be difficult for younger people to imagine this, but there was substantial segregation from the 1940s through the 1960s. Public water fountains and bathrooms were segregated. Hotels were, too. Black people could only sit in the balcony at movie theaters. Black people could not be served at lunch counters. They had to sit at the back of a bus. Hospitals had separate wards for black people, too. Much of the segregation was in the South, but by no means all of it. For example, a park in Pittsburgh, PA closed its swimming pool, rather than integrate it. Black entertainers in northern cities could not eat in the restaurants nor stay at the better hotels because they were segregated. A special road guide for black people who wanted to travel listed the places it was safe for them to stay or to eat. Southern schools were segregated, and it took federal troops to integrate them in Little Rock, Arkansas, the local opposition was so fierce. Brown v. Board of Education was not decided until 1955, so up to that point, school segregation was perfectly legal. And in fact, it was not until the Civil Rights Act of 1964 was passed that most segregation became unlawful. Even after the statute was passed, it took marches and protests and sit-ins to make the point.
