BOB DYLAN, NEWT GINGRICH and GLORIA STEINEM aren't on this list. They were born before 1946. MARTINA NAVRATILOVA and YO-YO MA aren't here either because both were born abroad. Those who did make it--chosen from 76 million eligible candidates born in the United States between 1946 and 1964--are an eclectic assortment of dropouts, geniuses, nerds, performers, and activists. One common thread: they've all had a major impact on life in America.
