What was it called in the 60"s

This property was acquired by the City of New York and authorized by the Board of Estimate on June 27, 1946 to be part of the Stephen Foster Houses. The housing project was named for Stephen Collins Foster (1826-1864), the American composer who penned, among other well-known songs, “O Susannah,” “Camptown Races” and “Beautiful Dreamer.” In November 1947 the property was designated as a playground, and five years later it was opened as the Stephen Foster Houses Playground. In May 1968, one month after King’s assassination, the surrounding housing complex was renamed the Martin Luther King, Jr. Towers, and the playground’s name was changed subsequently as well. This is what I found on google.

I wouldn't know. I'm not from Brooklyn
