Carter Godwin Woodson was an American historian, author, journalist and the founder of the Association for the Study of African American Life and History. He was one of the first scholars to study African-American history. A founder of The Journal of Negro History in 1916, Woodson has been cited as the "father of black history". In February 1926 he launched the celebration of "Negro History Week", the precursor of Black History Month.
Publius Cornelius Tacitus was a senator and a historian of the Roman Empire. The surviving portions of his two major works—the Annals and the Histories—examine the reigns of the Roman emperors Tiberius, Claudius, Nero, and those who reigned in the Year of the Four Emperors . These two works span the history of the Roman Empire from the death of Augustus, in 14 AD, to the years of the First Jewish–Roman War, in 70 AD. There are substantial lacunae in the surviving texts, including a gap in the Annals that is four books long.
