In comic books and other stories with a long history, first appearance refers to the first occurrence to feature a fictional character.

First appearances of popular characters are among the most valuable comic books in existence. In their spring 2002 issue, the editors of The Overstreet Comic Book Price Guide listed the ten most valuable comic books and seven were first appearances of popular superheroes. (Another, Marvel Comics #1 (October 1939), is the first appearance of the Golden Age Human Torch but it is probably more noteworthy because it was the first comic book published by industry giant Marvel Comics).

By the time a character is well-known; even iconic, many years have passed since his or her first appearance and few copies, and fewer good-conditioned copies, remain. These comic books may be worth thousands of dollars. In 2004, a copy of Flash Comics #1 (January 1940), the first appearance of The Flash, was auctioned for $42,000 and a copy of Captain America Comics #1 (March 1941), the first appearance of Captain America sold for $64,400. In 2010, another copy of Flash Comics #1 sold privately for $450,000.

Robin McLaurin Williams (born July 21, 1951) is an American actor and comedian. Rising to fame with his role as the alien Mork in the TV series Mork & Mindy, and later stand-up comedy work, Williams has performed in many feature films since 1980. He won the Academy Award for Best Supporting Actor for his performance in the 1997 film Good Will Hunting. He has also won two Emmy Awards, four Golden Globes, two Screen Actors Guild Awards and five Grammy Awards.

Williams was born in Chicago, Illinois. His mother, Laura McLaurin (née Smith, 1922–2001), was a former model from New Orleans, Louisiana. His father, Robert Fitzgerald Williams (September 10, 1906 – October 18, 1987), was a senior executive at Ford Motor Company in charge of the Midwest region. His maternal great-great-grandfather was senator and Mississippi governor Anselm J. McLaurin. Williams is of English, Welsh, Irish, and French ancestry. He was raised in the Episcopal Church (his mother practiced Christian Science). He grew up in Bloomfield Hills, Michigan, where he was a student at the Detroit Country Day School, and later moved to Woodacre, Marin County, California, where he attended the public Redwood High School. Williams studied at Claremont McKenna College (then called Claremont Men's College) for four years. He has two half-brothers: Todd (who died August 14, 2007) and McLaurin.

John William "Johnny" Carson (October 23, 1925 – January 23, 2005) was an American television host and comedian, known for thirty years as host of The Tonight Show Starring Johnny Carson (1962–1992). Carson received six Emmy Awards, the Governor Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987. Johnny Carson was awarded the Presidential Medal of Freedom in 1992 and received a Kennedy Center Honor in 1993.

Although his show was already successful by the end of the 1960s, during the 1970s Carson became an American icon and remained so until his retirement in 1992. He adopted a casual, conversational approach with extensive interaction with guests, an approach pioneered by Arthur Godfrey and previous Tonight Show hosts Steve Allen and Jack Paar. Late night hosts David Letterman, Jay Leno, Conan O'Brien, Craig Ferguson, and Jimmy Fallon have all cited Carson's influence on their late-night talk shows, which resemble his in format and tone.

Carson was born in Corning, Iowa, in the year 1925, to Homer Lloyd "Kit" Carson, a power company manager, and Ruth Hook Carson, who was of Irish descent. He grew up in the nearby towns of Avoca, Clarinda, and Red Oak in southwest Iowa before moving to Norfolk, Nebraska, at the age of eight. At the age of twelve, Carson found a book on magic at a friend's house and immediately purchased a mail-order magician's kit. He debuted as "The Great Carsoni" at fourteen and was paid $3; many other performances at local picnics and country fairs followed.
