On 23 April 2010, a memorial plaque was unveiled outside the Greater Binghamton Transportation Center bus terminal in Binghamton, New York, in honour of a mostly forgotten civil rights and mental health advocate who was murdered on that day 47 years prior.

William Lewis Moore, born in Binghamton on 28 April 1927, was a postal worker and member of the Congress of Racial Equality, who achieved a level of notoriety for staging lone protests against racial segregation in an era when few white people supported such causes.

Moore also became an advocate for mental health issues, a result of having been institutionalized for a year and a half after suffering a mental breakdown while a graduate student at John Hopkins University in the early 1950s. He would ultimately be diagnosed as suffering from schizophrenia.

Moore staged lone protests by marching to capital cities on three separate occasions to hand-deliver letters he’d written denouncing the practice of racial segregation. His first march was to Annapolis, the state capital of Maryland, followed by a march to the White House to deliver a letter to President John F. Kennedy, on the same day that Reverend Dr. Martin Luther King was released from the jail in Binghamton following protests in that city.
