Tuckerization (or tuckerism) is the act of using a person's name (and sometimes other characteristics)[citation needed] in an original story as an in-joke. The term is derived from Wilson Tucker, a pioneering American science fiction writer, fan and fanzine editor, who made a practice of using his friends' names for minor characters in his stories. For example, Tucker named a character after Lee Hoffman in his novel The Long Loud Silence, and after Walt Willis in Wild Talent.
In most cases, tuckerization is used for "bit parts" (minor characters), an opportunity for the author to create an homage to a friend or respected colleague. However, an author sometimes attaches a friend's name, description, or identifiable characteristics to a major character, and in some novels, nearly all characters represent friends, colleagues, or prominent persons the author knows. When that happens, tuckerization can rise to the level of a roman à clef.
Many science fiction authors auction off tuckerizations at science fiction conventions with the proceeds going to charity.
