author
Known from a late 19th-century historical work on African American contributions to U.S. freedom struggles, this author wrote with a clear purpose: to make overlooked service and sacrifice impossible to ignore.

by Prof. John Moore
Project Gutenberg lists Prof. John Moore as the author of What the Negro Has Done for Liberty in America, a historical work that argues for fuller recognition of Black Americans' role in the nation's fight for freedom.
From the surviving catalog information available here, the book focuses on African American contributions across major moments in U.S. history, including the Revolutionary War, the War of 1812, and the Civil War. The work appears aimed at correcting historical neglect and highlighting figures and soldiers whose service had often been minimized.
Reliable biographical details about Moore himself are scarce in the sources I could confirm during this search, so it seems best not to go beyond the evidence. The book remains the clearest window into his legacy: a forceful appeal to remember Black patriotism and courage as part of American history.
