The definitive history of the societal forces affecting blind people in the United States and the professions that evolved to provide services to people who are visually impaired, The Unseen Minority was originally commissioned to commemorate the fiftieth anniversary of the American Foundation for the Blind in 1971. Updated with a new foreword outlining the critical issues that have arisen since the original publication and with time lines presenting the landmark events in the legislative arena, low vision, education, and orientation and mobility, this classic work has never been more relevant.
