Book excerpt: A "must" introduction to significant African-American events & people in Massachusetts where so much American history began. The first slaves arrived in Boston in 1638; the first Black gave his life in the Boston Massacre. Entries are dramatic bullet-style cameos set off by more than 100 photographs. Arranged chronologically within a dozen categories--Science, Religion, Government, Creative Arts, among them--the elegantly designed paperback offers instant identification of names & invites follow up research--a catalyst "to find out more." Among the entries: a high school student wins ten dollars in gold for her essay on the "Evils of Intemperance"; a physician fights for the right to deliver babies at the city hospital; Blacks unite in protest against the film BIRTH OF A NATION; a Boston mechanic invents a diving suit & a dentist invents a golf tee. The BOSTON GLOBE calls it a book that explores the "rich heritage & legacy of leaders who lived here but had an impact upon all America--including Frederick Douglass, William DuBois, Phillis Wheatley, Malcolm X, Dr. Martin Luther King, Jr." An executive of Bank of Boston, which funded the publication, calls it "a book about dreams." And the dreams came true. Available through Publisher's Sales Office--666 Boylston Street, Boston, MA 02116, Tele-(617)-536-5400. xt 346.
