Since the 1960s, many historians have condemned Booker T. Washington as a problematic, even negative, influence on African American progress. This attitude dramatically contrasts with the nationwide outpouring of grief and reverence that followed Washington's death in 1915. Kenneth M. Hamilton describes how, when, where, and why Americans commemorated the life of Booker T. Washington. For months following his death, tens of thousands of Americans, especially blacks, honored his memory. Their memorials revealed that Washington enjoyed widespread national support for his vision of America and the programs that he imparted to achieve his aspirations. Their actions and articulations provide rich insight into how a cross section of Washington's contemporaries viewed him. From private messages of solace to public pronouncements, countless Americans portrayed him as a revered national icon. Among other characteristics, commemorates voiced their appreciation of his humanitarianism, humility, nationalism, perseverance, philanthropy, progressivism, spirituality, and wisdom. Washington was the leading advocate of the Yankee Protestantism Ethic, which promoted education, and personal qualities such as pragmatism, perseverance, cleanliness, thrift, and the dignity of labor among African Americans.
