The early 20th century is recalled. Included are profiles of Irving Berlin, the writer of "White Christmas"; Supreme Court Justice Louis Brandeis; Gertrude Berg, who created the "Goldbergs" radio and TV series; and Henry Morgenthau, who served as treasury secretary in FDR's cabinet. Also: the rise of the Hollywood movie studios; the popularity of the Catskills, where comedy---and food---ruled; the anti-semitism Jews faced in the U.S. from the likes of Henry Ford; the Leo Frank case.
