In 1969, the year he graduated from Brooklyn Law School, Rivera decided to become a poor people's lawyer, and over the next 12 months he took part in 50 trials, most of them in criminal courts. Then his career took an abrupt turn: in June 1970 he was offered a job at WABC-TV's _Eyewitness News_, and Rivera quickly accepted. His aggressive, probing style, matchless reportorial skills, and charismatic presence gained him the Associated Press' first-place citation as top newsman of 1971 -- an award he received three more times in the next four years. In 1975 he became the traveling co-host of _Good Morning America_ on ABC network; in the 20 months that followed, his assignments took him to more than two dozen countries. Continuing his upward climb, he was next transferred to the _ABC Evening News_ with Barbara Walters and Harry Reasoner. Finally in 1978, he was named to his present position -- as special correspondent for _20/20_, ABC's weekly hour-long news magazine show. Over the past nine years, Rivera's special reports have earned him virtually all the major awards in broadcast journalism, including several Emmys. It was one of his earliest documentaries, however, that brought him the most recognition. Titled _Willowbrook: The Last Great Disgrace_, the 1972 expose focused on the conditions at Staten Island's Willowbrook institution for the mentally retarded. The broadcast resulted in an unprecedented response from viewers. So many offers of assistance poured in that Rivera was able to set up a national organization known as One to One, whose goal is to give ongoing, individualized attention to retarded persons. Since 1973, One to One has raised more than $2 million, and helped to build almost 60 group homes throughout the New York metropolitan area, each housing approximately 12 retarded persons of the same general age range. On June 6 from 8 to 10:30 p.m., One to One will present a TV special that will combine top entertainment with personal accounts of retarded people, their parents, and the role of the media in helping to shape public awareness. The entertainers include Paul McCartney and Wings, Neil Sedaka, Debby Boone, Ed Asner, Angela Lansbury and the Captain & Tennille. Geraldo Rivera shares the emceeing chores with his ABC colleague John Johnson. "The show will be both taped and live," says Rivera in an interview at his West 60th Street office. "We've designed the program so that it's not a classic telethon where every two seconds they say, 'Please send us your money.'" Among the more dramatic moments is a tape of the Seventh Annual Wall Street Charity Fund Boxing Match, which raised thousands of dollars for One to One. "For the first year, I'm not the main event," comments Rivera, who scored a technical knockout over his opponent in 1978. "My nose was broken last year, and they took out all the scar tissue. They decided that my nose had given enough for the cause."
