Jan Leighton, an actor who conjured a career by dressing up as historical figures, appearing in so many commercials, print advertisements and industrial films as George Washington, William Shakespeare and Christopher Columbus that he was both ubiquitous and anonymous, died on Nov. 16 in Manhattan. He was 87.

The cause was complications after a stroke, said his daughter, Hallie.

Mr. Leighton, who was listed in the 1985 Guinness Book of World Records as the actor who had played the most roles (2,407), began his professional career as a legitimate actor, appearing on live television dramas and at least once on Broadway, in a 1960 Cy Coleman musical called “Wildcat,” starring Lucille Ball. But when the jobs became scarce, he reinvented himself as a walking, talking hall of fame, an impersonator for hire. He researched the characters, created his own costumes  he had more than 400 of them in his Manhattan apartment when he died  and often did his own makeup.

In disguise, Mr. Leighton might pop up in almost any medium. On television, he lit a cigar as Fidel Castro in a commercial for Bic lighters and sold Toyotas as Albert Einstein for a Southern California car dealership. He promoted a Minnesota savings bank as Abraham Lincoln and an Arizona department store as Robert E. Lee. For one bank commercial he portrayed Clark Gable, Groucho Marx, Teddy Roosevelt and Franklin Delano Roosevelt, all complaining about other banks that charged for checks. He pitched Cheerios as Alexander Hamilton, beer as Johann Sebastian Bach, early mobile phones as Dracula and cough syrup as the Frankenstein monster. He even played Mr. Whipple’s twin in a commercial for Charmin bathroom tissue.

On film, he played Albert Einstein in a 1982 science fiction comedy “Zapped!” He motivated Westinghouse employees as George Washington and the salesmen of Scania trucks as Gen. George Patton. In print he appeared twice on the cover of New York magazine, once as Henry Kissinger and once as Leonardo da Vinci; he was Uncle Sam on the cover of Time. He was the face of Saul Bellow’s title character “Henderson the Rain King” on a paperback edition of the book, and appeared as a host of characters, including Confucius and Pericles, on the book jacket of Gore Vidal’s “Creation.” He made appearances at gala events and private parties as presidents and wizards and such.
