Held since 1978, the tournament is the oldest professional women's indoor tournament in Europe. The event was part of theTier II category from 1990 until 2008 and as of 2009 has been aPremier tournament on theWTA Tour.[1] The singles champion receives prize money and aPorsche sports car.[2] Until 2008 the tournament was played onhardcourt in autumn.

The tournament has been won by many formernumber ones and Grand Slam champions.Martina Navratilova holds the record for most singles wins at the event, with six titles between 1982 and 1992, in addition to eight doubles titles.Tracy Austin andMartina Hingis both come second with four wins each in the singles event, with Austin winning four consecutive. This is followed byLindsay Davenport andMaria Sharapova with three wins each.
The tournament was founded by businessman Dieter Fischer who had organized a men's exhibition tournament[a] in Filderstadt in 1977 to open his tennis centre.[4] After failing to schedule a men's event in 1978 a license for aTier II women's tournament was purchased for $100,000 and the first edition was held in October 1978, won by 15-year oldTracy Austin.[5] In March 1979 a men's tournament was held, won byWojciech Fibak, but this event was discontinued as it required too much effort to organize two tournaments annually with a volunteer force. In 1992 a request for promotion to theTier I category was rejected by the WTA on the grounds that the tournament's centre court, with a 3,000-seat capacity, was too small.[1] In 2002 Fischer sold the tournament licence to Porsche who had been the official sponsor since the first edition.[6]
