The Black Panther's name predates the October 1966 founding of the Black Panther Party, though not the black panther logo of the party's predecessor, the Lowndes County Freedom Organization (LCFO), nor the segregated World War II 761st "Black Panthers" Tank Battalion.[2][3] Co-creator Stan Lee denied that the comic, which pre-dates the political usage of the term, was, or could have been, named after any of the political uses of the term "black panther", including the LCFO, citing "a strange coincidence".[4]
