In 1959, police were called to a segregated library in S. Carolina when a 9yr-old black boy refused to leave. He later got a PhD in Physics from MIT, and died in 1986, one of the astronauts aboard the space shuttle Challenger. The library that refused to lend him books is now named after him.
The Pentagon was constructed with twice the number of bathrooms needed for the number of employees because segregated Virginia at the time required separate facilities for “white” and “colored” persons.
New York’s public schools are now more segregated than Mississippi’s.
