According to an article in New Jersey Monthly, Martin Luther King Jr.’s Camden residence has been saved from demolition, thanks in large part to the efforts of local car salesman Patrick Duff, an amateur historian who documented the home’s historic significance.

King lived in the house from the end of 1948 to 1951, while attending Crozer Theological Seminary in Chester, Pennsylvania. His Camden residency had been all but forgotten until Duff, investigating a related matter, happened upon the legal complaint signed by King following a June 12, 1950, incident in nearby Maple Shade.
