Carter G. Woodson and the organization he founded, the Association for the Study of Negro Life and History (ASNLH), conceived and announced Negro History Week in 1925. The event was the first celebrated during a week in February 1926 that encompassed the birthdays of both Abraham Lincoln and Frederick Douglass. The response was overwhelming: Black history clubs sprang up; teachers demanded materials to instruct their pupils; and progressive whites, not simply scholars and philanthropists, stepped forward to endorse the effort. By the time of Woodson's death in 1950, Negro History Week had become a central part of African American life and substantial progress had been made by bringing more Americans to appreciate the celebration. At mid-century, mayors of cities nationwide issued proclamations noting Negro History Week. The Black Awakening of the 1960s dramatically expanded the consciousness of African Americans about the importance of black history, and the Civil Rights movement focused Americans of all color on the subject of the contributions of African Americans to our history and culture. The celebration was expanded to a month in 1976, the nation's bicentennial. President Gerald R. Ford urged Americans to "seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history." That year, fifty years after the first celebration, the association held the first African American History Month. By this time, the entire nation had come to recognize the importance of Black history in the drama of the American story. Since then each American president has issued African American Heritage Month proclamations.
