A stage name is a pseudonym used by performers and entertainers such as actors, comedians, singers, and musicians. Such titles are adopted for a wide variety of reasons, and may be similar or nearly identical to an individual's birth name. In some situations, though not often, a performer will adopt their title as a legal name. Nicknames and maiden names are sometimes used in a person's professional name.
Reasons for using a stage name
A performer will often take a stage name because their real name is considered unattractive, dull, or unintentionally amusing; projects an undesired image; is difficult to pronounce or spell; or is already being used by another notable individual, including names that are not exactly the same but still too similar. An example of that is pop singer Katy Perry's real name is Katy Hudson, which would've caused confusion for the actress Kate Hudson. Sometimes a performer adopts a name which is unusual or outlandish to attract attention. Other performers use a stage name in order to retain anonymity, as is often the case for porn stars, especially if they intend on switching careers. The equivalent concept among writers is called a nom de plume (pen name). In radio, the term "radio name" or "air name" is used.
Some individuals who are related to a celebrity take a different last name so they are not perceived to have received undue advantage from their family connection. Actor Nicolas Cage, born Nicolas Coppola, chose a new last name to avoid comparisons with his uncle, director Francis Ford Coppola, who gave him his big break in the movie Peggy Sue Got Married.
Conversely, individuals who wish to receive benefit from their family connections may take that person's first or last name. Lon Chaney Sr.'s son Creighton spent a number of years appearing in minor roles before renaming himself Lon Chaney Jr. Likewise, Emilio Estevez and his sister Renee chose not to take their father Martin Sheen's professional name and use their birth names; however, their brother Carlos chose to use their father's professional name, and took the name Charlie Sheen. Some children born outside marriage to a (usually male) celebrity parent have done the same: Jett Williams (née Antha Bell Jett) and Scott Eastwood (né Scott Clinton Reeves) each use their father's last name.
Women who achieve fame after marriage often use their married name as part of their professional name, while women who achieved fame before marriage may continue to use their maiden name or a hyphenated surname.
In some cases, the individual may adopt a stage name to avoid confusion with other family members who have similar names. Actor Mark Harmon (Thomas Mark Harmon) uses his middle name professionally to avoid confusion with his father Heisman Trophy winner and former broadcaster Tom Harmon (Thomas Dudley Harmon).
Guilds and associations that represent actors, such as the Screen Actors Guild (SAG) in the United States and British Actors' Equity Association in the United Kingdom, stipulate that no two members may have identical working names. An actor whose name has already been taken must choose a new name.
Notable examples include: Nathan Lane, whose birth name (Joseph Lane) was already in use; Stewart Granger, born James Stewart; and Michael Keaton, born Michael Douglas. Diane Keaton, whose birth name is Diane Hall, took her mother's maiden name as a stage name after learning that there was already a registered actress named Diane Hall in the Actors' Equity Association. Ugly Betty actress Vanessa Williams officially uses "Vanessa L. Williams" due to SAG guidelines, although the other actress with same first and last name (Vanessa E. Williams) is arguably less notable. Similarly, David Walliams changed one letter in his surname due to there being another "David Williams". Terry O'Quinn of Lost fame changed his surname from Quinn to O'Quinn as another registered actor already had the name Terrance Quinn. Long-time Simpsons writer and Futurama executive producer David X. Cohen changed his middle initial from S to X because there was already a David S. Cohen registered with the Writer's Guild of America. Julianne Moore was born Julie Anne Smith but found that all variations of that name were already used by other actors.
A middle name may be adopted in preference to changing a name. In some cases, attaching a generational suffix is sufficient for guild rules; broadcaster David Lawrence is credited as David H. Lawrence XVII as a result of there being sixteen other David Lawrences in show business at the time he received his SAG card.
A person hoping to become successful as an entertainer who has a name identical to a name already familiar to the public (in any field of endeavor) may change his/her name in order to avoid having his/her name evoke the other person with the same name. Singer Katy Perry, born Katheryn Elizabeth Hudson, released her self-titled album under the name Katy Hudson, but later used her mother's maiden name to avoid confusion with actress Kate Hudson.
Involuntary name changes
A performer may also have had their stage name chosen for them by their agent – such was the case with Barbara Eden, born Barbara Jean Huffman[contradictory] – or, in the heyday of the Hollywood studios, by a movie studio. Joan Rivers (born Joan Alexandra Molinsky) went one step further and named herself after a former agent, Tony Rivers, after he told her to change her name. In the non English-speaking world, an example is the Taiwanese Mandopop girl group S.H.E (composed of Selina Jen, Hebe Tian, and Ella Chen), whose members' English names were chosen by their manager after taking personality tests.
Former child star Patty Duke (whose real name is Anna Marie Duke) had her stage name chosen for her by her first managers. Their choice of the name "Patty" was inspired by another child actress named Patty McCormack.
Cary Grant (born Archibald Alec Leach) had his name selected for him by Paramount Pictures. He had been using the name "Cary Lockwood", but the studio decided against it, deeming it too similar to another actor working at the time. Cary and the studio eventually settled on "Cary Grant" (Grant thought the letters "C" and "G" to be lucky: they had brought previous success for both Clark Gable and Gary Cooper). Joan Crawford, born Lucille Fay LeSueur, had her name changed as a result of a magazine poll organised by her studio, MGM.
In the past, a stage name was often used when a performer's real name was considered to denote a specific ethnicity that faced potential discrimination. In other cases, actors have reinvented themselves with a more ethnic identity, when that gave them an advantage in playing "ethnic" roles.
Historically, Jews in Hollywood were encouraged to anglicize their names to avoid possible discrimination. Examples of such name changes are Danny Kaye and Mel Brooks, both of whom were born with the surname Kaminsky, the original two lineups of The Three Stooges (born the Horwitz brothers and Louis Feinburg) and Woody Allen (born Allen Konigsberg). Jon Stewart claims that he did not anglicize his name for career reasons, but because of his estranged relationship with his father. Israeli-American Natalie Portman changed her name allegedly to protect her privacy.
Ramón Estévez changed his name to Martin Sheen as he felt it affected his job prospects due to racial discrimination and bias, although he maintains his birth name for legal documents such as his passport; his sons made divergent choices: Carlos Irwin Estévez is now Charlie Sheen, while Emilio Estevez left his name unchanged. German-born actor Hans Gudegast adopted the stage name of Eric Braeden.
Actors Anthony Quinn and Anne Bancroft were advised to anglicize their names because 'Antonio Rodolfo Quinn Oaxaca' and 'Anna Maria Louisa Italiano', respectively, were considered too 'ethnic' for Hollywood and Broadway at the time. Eydie Gorme (born Edith Garmezano), Sophia Loren (born Sofia Villani Scicolone), Charles Bronson (born Charles Dennis Buchinsky), and Rita Hayworth (born Margarita Carmen Cansino), are four more well-known examples of this trend.
Broadcaster Dave Roberts was born David T. Boreanaz but was known professionally as Dave Thomas and later Dave Roberts as ethnic surnames were discouraged when he first began his career during the 1950s; his son, actor David Boreanaz, chose not to adopt a stage name.
The use of stage names for ethnic purposes may vary widely depending on the media market the personality is representing. For example, in Buffalo, New York, a city with a large Polish-American population, Polish-American media personalities typically work freely using their birth names.
Sicilian-American actor Espera Oscar de Corti, who built his film career portraying Native Americans, reinvented himself as Iron Eyes Cody. He not only took his stage name as his legal name, but eventually began insisting that he actually was Native American.
Actress Bernadette Peters (born Bernadette Lazzara) was encouraged as a child actress to use her father's first name, Peter as her last name by her mother to avoid being type-cast in Italian roles.
Chloe Bennet had used her birth name, Chloe Wang, for her singing career in China. She started using the surname Bennet, after her father's first name, when she failed to be welcomed by Hollywood agents.
Ease of use
Another consideration in choosing a stage name is ease of use. The Actors' Equity Association (AEA) advises performers to select a name that is easy for others to pronounce, spell, and remember. Some performers, while paying great attention to their skills and abilities, give little thought to the difference that a well-thought-out name can make to their career. Often a person or group decides on a different name only after they realize that a poorly chosen name gives a bad impression.
Actor Michael Caine was born Maurice Micklewhite and chose the name "Michael" because he preferred the sound of it to the less glamorous-sounding "Maurice". He reputedly chose the name "Caine" because at that precise instant he saw a cinema marquee for the then-current movie The Caine Mutiny, and thought that it would make a good last name in conjunction with Michael. ("Had I looked the other direction," he later quipped, "I'd be known as Michael The One Hundred and One Dalmatians.") Similarly, actor Pete Postlethwaite was advised to adopt a different surname by peers who quipped that his "would never be put up in lights outside theaters because they couldn't afford the electricity" (Postlethwaite rejected the advice). Conversely, Doris Kappelhoff heeded the suggestion of a bandleader who said that her name would never fit on the marquee; since "Day By Day" had become a signature song for her, she became known to the public as Doris Day.
Relevance to image
Ching Lau Lauro (flourished 1827–1839) used a Chinese stage name to represent his stage image as a contortionist in Chinese costume. He was probably the first magician to dress in Chinese costume on stage.
Commonly in the music world, and especially those of heavy metal, punk rock, industrial, and hip hop, musicians will rename themselves with names more menacing or striking than their birth names. Every member of the punk band Ramones took the pseudonymous "Ramone" surname as part of their collective stage persona. Members of New Zealand art-rock band Split Enz all took their middle names as stage names, so as to keep their private image separate from their public personae.
Other performers may assume stage names as a means of distancing themselves from publicly known childhood names that could be considered professionally embarrassing, outlandish, or otherwise inappropriate. Film director Duncan Jones (son of singer David Bowie) was known publicly as a child as Zowie Bowie.
Hip-hop artists are known to use stage names, such as Jay-Z (born Shawn Carter), 50 Cent (born Curtis Jackson), Diddy (born Sean Combs), Ludacris (born Chris Bridges), Lil Wayne (born Dwayne Carter Jr.), and Soulja Boy (born DeAndre Way). At times, these artists will use their real names to make promoted material seem more authentic or personal. Eminem has used his real name, Marshall Mathers, in various public events and as an alter ego as his real name gained recognition following the release of his multi-platinum album, The Marshall Mathers LP. Similarly, LL Cool J released the albums Mr. Smith and Todd Smith in 1995 and 2006, respectively, under his real name, James Todd Smith. Rapper-singer-actress Queen Latifah released The Dana Owens Album under her own given name, Dana Owens, after changing her musical focus from hip-hop to vocal jazz. Rapper and sometime actor Xzibit has been credited by his real name Alvin Joiner in several television shows.
Euphony and ease of remembrance
Some performers and artists may choose to simplify their name to make it easier to spell and pronounce, and easier for others to remember. For instance, Fall Out Boy vocalist and guitarist Patrick Stump removed the "h" from his original name, Stumph. It was still pronounced "stump", but the change ensured his audience wouldn't think to pronounce it "stumf". Singer Jason Derulo uses the phonetic spelling of his given name, Jason Desrouleaux.
Andy Warhol dropped an "a" from his original name, Warhola, while couturier Yves Mathieu-Saint-Laurent dropped the first of his two surnames. Rodolfo Alfonso Raffaello Piero Filiberto Guglielmi adopted the stage name Rudolph Valentino in part because American casting directors found his original surname difficult to pronounce. Singer George Michael (the son of a Greek Cypriot restaurateur in North London) was born Georgios Kyriacos Panayiotou.
Some surnames may carry unfortunate connotations. Hal Linden, born Harold Lipshitz, adopted his stage name for fear that the embedded obscenity in his original surname could cost him work. Ralph Lauren's brother (who was his guardian) changed their family name from Lifshitz for a similar reason: fear of mockery. Duran Duran's Nick Rhodes, born Nicholas James Bates, changed his name to escape childhood ridicule (as a child, children would often tease him by calling him "Master Bates"; he adopted the surname "Rhodes" after a brand of keyboard). Diana Dors was born Diana Fluck (one letter away from a profanity); this prompted her to change her name to a more benign one in order to avoid an accidental obscenity (which could have been exacerbated by her status as a sex symbol).
Some types of music are more associated with stage names than others. For example, hip hop and EDM artists almost always use stage names, whereas "classical" composers and performers virtually never do. Classical violinist Amadéus Leopold (born in South Korea as Yoo Hanbin) and opera singers Beverly Sills (born Belle Miriam Silverman) and Nellie Melba (born Helen Porter Mitchell) are rare exceptions.
Some performers take a series of different stage names. The British pop singer successful in the 1970s as Alvin Stardust previously went by the stage name of Shane Fenton in the 1960s. He had been born Bernard William Jewry. Some performers will use different names in different settings. Charles Thompson, singer-songwriter for the alternative band the Pixies, was known in that band as Black Francis. He was called Frank Black as a solo performer, and again called Black Francis in a reunited Pixies.
Unlike Hollywood stage names, many musical artists' stage names are obviously not personal names, but they may still end up universally used to refer to the performer, such as Lady Gaga. At times the line may be blurred between the name of an act and the stage name of the lead.
Many performers refer to their stage name as their "professional name". In some cases, performers subsequently adopt their stage name as their legal name. For instance, the former Robert Allen Zimmerman's legal name has been Robert Dylan (Bob Dylan) since he changed it in New York City Supreme Court in August 1962. Elton John was born Reginald Kenneth Dwight but changed his name by deed poll, making Elton Hercules John his real name. When he was knighted, he became Sir Elton Hercules John rather than Sir Reginald Kenneth Dwight. Elvis Costello (born Declan MacManus), who had adopted his professional name as a legal name, changed it back to his birth name in 1986. Another example is Marvin Lee Aday, known by his stage name Meat Loaf.  In a similar way, actress and singer Miley Cyrus was born Destiny Hope Cyrus but found "Miley" more comfortable, making it her legal name.
