Book excerpt: Barack Obama is the first African American President, but the history of African Americans in the White House long predates him. The building was built by slaves, and African Americans have worked in it ever since, from servants to advisors. In charting the history of African Americans in the White House, Kenneth T. Walsh illuminates the trajectory of racial progress in the US. He looks at Abraham Lincoln and his black seamstress and valet, debates between President Johnson and Martin Luther King over civil rights, and the role of black staff members under Nixon and Reagan. Family of Freedom gives a unique view of US history as seen through the experiences of African Americans in the White House.
