For Coming of Age, the Pulitzer Prize-winning author and Peabody Award-winning radio host--himself an octogenarian--has interviewed several very different men and women ranging in age from 70 to 99. Some are powerful celebrities (Maggie Kuhn of the Grey Panthers, economist John Kenneth Galbraith); others are obscure people in small towns. Together they represent an extraordinary panorama of American life and work throughout this century and the ways in which the times have changed.
