Question: Who is the author of the book named after the performer who inspired Beyoncé to take control of her career?

full_context: Document 1: Madonna (entertainer): Madonna has received acclaim as a role model for businesswomen in her industry, "achieving the kind of financial control that women had long fought for within the industry", and generating over $1.2 billion in sales within the first decade of her career. Professor Colin Barrow from Cranfield School of Management described Madonna as "America's smartest businesswoman ... who has moved to the top of her industry and stayed there by constantly reinventing herself." London Business School academics called her a "dynamic entrepreneur" worth copying; they identified her vision of success, her understanding of the music industry, her ability to recognize her own performance limits (and thus bring in help), her willingness to work hard and her ability to adapt as the keys to her commercial success. Morton wrote that "Madonna is opportunistic, manipulative, and ruthless—somebody who won't stop until she gets what she wants—and that's something you can get at the expense of maybe losing your close ones. But that hardly mattered to her." Hazel Blackmore and Rafael Fernández de Castro in the book ¿Qué es Estados Unidos? from the Fondo de Cultura Económica, noted: "Madonna has been undoubtedly the most important woman in the history of popular music and a great businesswoman in herself; creating fashion, breaking taboos and provoking controversies."
Document 2: Madonna (entertainer): In The Madonna Companion biographers Allen Metz and Carol Benson noted that more than any other recent pop artist, Madonna had used MTV and music videos to establish her popularity and enhance her recorded work. According to them, many of her songs have the imagery of the music video in strong context, while referring to the music. Cultural critic Mark C. Taylor in his book Nots (1993) felt that the postmodern art form par excellence is video and the reigning "queen of video" is Madonna. He further asserted that "the most remarkable creation of MTV is Madonna. The responses to Madonna's excessively provocative videos have been predictably contradictory." The media and public reaction towards her most-discussed songs such as "Papa Don't Preach", "Like a Prayer", or "Justify My Love" had to do with the music videos created to promote the songs and their impact, rather than the songs themselves. Morton felt that "artistically, Madonna's songwriting is often overshadowed by her striking pop videos."
Document 3: Beyoncé: In an interview published by Vogue in April 2013, Beyoncé was asked if she considers herself a feminist, to which she said, "that word can be very extreme... But I guess I am a modern-day feminist. I do believe in equality". She would later align herself more publicly with the movement, sampling "We should all be feminists", a speech delivered by Nigerian author Chimamanda Ngozi Adichie at a TEDxEuston conference in April 2013, in her song "Flawless", released later that year. She has also contributed to the Ban Bossy campaign, which uses television and social media to encourage leadership in girls.
Document 4: Beyoncé: Beyoncé has received praise for her stage presence and voice during live performances. Jarett Wieselman of the New York Post placed her at number one on her list of the Five Best Singer/Dancers. According to Barbara Ellen of The Guardian Beyoncé is the most in-charge female artist she's seen onstage, while Alice Jones of The Independent wrote she "takes her role as entertainer so seriously she's almost too good." The ex-President of Def Jam L.A. Reid has described Beyoncé as the greatest entertainer alive. Jim Farber of the Daily News and Stephanie Classen of Star Phoenix both praised her strong voice and her stage presence.
Document 5: Beyoncé: Beyoncé has stated that she is personally inspired by US First Lady Michelle Obama, saying "She proves you can do it all" and she has described Oprah Winfrey as "the definition of inspiration and a strong woman".

Beyoncé has expressed admiration for the artist Jean-Michel Basquiat, posting in a letter "what I find in the work of Jean-Michel Basquiat, I search for in every day in music... he is lyrical and raw". In February 2013, Beyoncé said that Madonna inspired her to take control of her own career. She commented: "I think about Madonna and how she took all of the great things she achieved and started the label and developed other artists. But there are not enough of those women.".

Document 14: Madonna (entertainer): Life with My Sister Madonna, a book by Madonna's brother Christopher, debuted at number two on The New York Times bestseller list. The book caused some friction between Madonna and her brother, because of the unsolicited publication. Problems also arose between Madonna and Ritchie, with the media reporting that they were on the verge of separation. Ultimately, Madonna filed for divorce from Ritchie, citing irreconcilable differences, which was finalized in December 2008. She decided to adopt from Malawi. The country's High Court initially approved the adoption of Chifundo "Mercy" James; however, the application was rejected because Madonna was not a resident of the country. Madonna appealed, and on June 12, 2009, the Supreme Court of Malawi granted Madonna the right to adopt Mercy James. She also released Celebration, her third greatest-hits album and final release with Warner. It contained the new songs "Celebration" and "Revolver" along with 34 hits spanning her career.

Document 15: Madonna (entertainer): Various music journalists, critical theorists, and authors have deemed Madonna the most influential female recording artist of all time. Author Carol Clerk wrote that "during her career, Madonna has transcended the term 'pop star' to become a global cultural icon." Rolling Stone of Spain wrote that "She became the first viral Master of Pop in history, years before the Internet was massively used. Madonna was everywhere; in the almighty music television channels, 'radio formulas', magazine covers and even in bookshops. A pop dialectic, never seen since The Beatles's reign, which allowed her to keep on the edge of tendency and commerciality." Laura Barcella in her book Madonna and Me: Women Writers on the Queen of Pop (2012) wrote that "really, Madonna changed everything the musical landscape, the '80s look du jour, and most significantly, what a mainstream female pop star could (and couldn't) say, do, or accomplish in the public eye." William Langley from The Daily Telegraph felt that "Madonna has changed the world's social history, has done more things as more different people than anyone else is ever likely to." Alan McGee from The Guardian felt that Madonna is a post-modern art, the likes of which we will never see again. He further asserted that Madonna and Michael Jackson invented the terms Queen and King of Pop.
