PRINCETON, N.J. (AP) _ Carmen ''Irish'' Fasanella first outfitted the back of his Buick truck in 1919 with two planks that served as benches to ferry Princeton University students to campus from the local train station.

Fasanella, 87, who retired in October after logging 68 years, 243 days as a cabby, was told last week by the Guinness Book of World Records that he is the world's longest licensed taxi driver, breaking the previous mark by more than a decade.

The former record-holder, Francis Edward Kenyon of Manchester, England, held his taxi license 57 years-plus, from 1924 to 1981.

Fasanella has driven for Jimmy Stewart, Adlai Stevenson and F. Scott Fitzgerald, but his favorite rider was Albert Einstein, who lived in Princeton and worked at the Institute for Advanced Studies.

The scientist enlisted the cabby as a sort of bodyguard for his morning walks.

''He was a terrific guy and a wonderful, wonderful man,'' Fasanella said. ''People used to scare him half to death. People would be riding up Mercer Street 40 or 50 mph, throw their breaks on, jump out of the car and run towards him to get an autograph. They used to scare the poor old man to death.''

Fasanella said sometimes he would walk with Einstein, and sometimes he would follow behind in his cab to ward off curiosity seekers.
