Stefanie Graf was born on 14 June 1969, in Mannheim, Baden-Wurttemberg, West Germany, to Heidi Schalk and Peter Graf (18 June 1938 - 30 November 2013), a car and insurance salesman. When she was nine years old her family moved to the neighbouring town of Bruhl. She has a younger brother Michael. Graf was introduced to tennis by her father, an aspiring tennis coach, who taught his three-year-old daughter how to swing a wooden racket in the family's living room.
The main weapons in Graf's game were her powerful inside-out forehand drive (which earned her the moniker Fraulein Forehand) and her intricate footwork. She often positioned herself in her backhand corner and although this left her forehand wide open and vulnerable to attack, her court speed meant that only the most accurate shots wide to her forehand caused any trouble. Graf's technique on the forehand was unique and instantly recognizable: generating considerable racquet head speed with her swing, she reached the point of contact late and typically out of the air. As a result, she hit her forehand with exceptional pace and accuracy. According to her coaches Pavel Slozil and Heinz Gunthardt, Graf's superior sense of timing was the key behind the success of her forehand.  Graf also had a powerful backhand drive but over the course of her career tended to use it less frequently, opting more often for an effective backhand slice. Starting in the early 1990s, she used the slice almost exclusively in baseline rallies and mostly limited the topspin backhand to passing shots. Her accuracy with the slice, both cross-court and down the line and her ability to skid the ball and keep it low, enabled her to use it as an offensive weapon to set the ball up for her forehand put-aways. However, Graf admitted in 1995 that she would have preferred having a two-handed backhand in retrospect.  She built her powerful and accurate serve up to 174 km/h (108 mph), making it one of the fastest serves in women's tennis and was a capable volleyer.  An exceptionally versatile competitor, Graf remains the only player, male or female, to have won the calendar-year Grand Slam on three surfaces or to have won each Grand Slam at least four times. Eighteen-time Grand Slam champion and former rival Chris Evert opined, "Steffi Graf is the best all-around player. Martina [Navratilova] won more on fast courts and I won more on slow courts, but Steffi came along and won more titles on both surfaces." Her endurance and superior footwork allowed her to excel on clay courts, where, in addition to six French Open titles, she won 26 regular tour events, including a record eight titles at the German Open. Meanwhile, her naturally aggressive style of play, effective backhand slice and speed around the court made her even more dominant on fast surfaces such as hard courts, grass and carpet. Graf stated that grass was her favorite surface to play on, while clay was her least favorite.

did her husband ever influence her style?





Answer the question at the end by quoting:

Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.
The script took Schaefer four years to write, but when it was finished, the film came together quickly. With the help of producers Alexandra Milchan and Robert Salerno, Schaefer cast Jared Leto as Mark David Chapman. For his role, Leto gained 67 pounds (30 kg) by drinking microwaved pints of ice cream mixed with soy sauce and olive oil every night. Gaining the weight, he said, was tougher than dieting himself into skeletal shape for his role as drug addict Harry Goldfarb in Requiem for a Dream (2000). The abruptness of Leto's weight gain gave him gout. He had to use a wheelchair due to the stress of the sudden increase in weight put on his body.  After the shooting of the film, Leto quickly went on a liquid diet. He explained, "I've been fasting ever since. I've been doing this very strange, like, lemon and cayenne pepper and water fast. I didn't eat any food for 10 days straight; I think I lost 20 pounds that first 10 days." Losing the excess weight after Chapter 27 proved a challenge. "It took about a year to get back to a place that felt semi-normal," he said; "I don't know if I'll ever be back to the place I was physically. I'd never do it again; it definitely gave me some problems."  Twenty-two years prior to this film's production, actor Mark Lindsay Chapman, while professionally using the name Mark Lindsay, had been almost cast as John Lennon in the biopic John and Yoko: A Love Story (1985). Yoko Ono had been deeply involved in the production and had herself been initially impressed with his audition and approved his casting prior to discovering his full name was Mark Lindsay Chapman. She then nixed his casting on the grounds it was "bad karma", and a great deal of press attention was given to his having almost gotten the role. The director of Chapter 27, Jarrett Schaefer, auditioned many Lennon impersonators, but was especially impressed with Mark Lindsay Chapman's tape because he conveyed the "tough town" street-smart quality of Lennon that the impersonators failed to convey, as they always played Lennon as larger-than-life. Schaefer described Lennon as having a "chip on his shoulder and always cracking these cynical one-liners", and felt that actor Chapman was best at conveying this quality. Schaefer had some difficulty negotiating the casting with the film's producers because of Chapman's name. After Chapman was cast, he asked Chapman how he should be billed to which Chapman replied "Mark fucking Lindsay Chapman. That's my fucking name." Schaefer remarks that this was so reflective of how Lennon talked, it just reinforced his sense that Chapman was right for the part.
