Susanne Klatten (born Susanne Hanna Ursula Quandt on 28 April 1962) is a German heiress, the daughter of Herbert and Johanna Quandt. As of June 2019, her net worth was US$18.8 billion, making her the richest woman in Germany and the 52nd richest person in the world.
Klatten was born in Bad Homburg, Germany. After gaining a degree in business finance, she worked for the advertising agency Young & Rubicam in Frankfurt from 1981 to 1983. This was followed by a course in marketing and management at the University of Buckingham, and an MBA from IMD in Lausanne specialising in advertising.
She gained further business experience in London with Dresdner Bank, the Munich branch of management consultants McKinsey and the bank Bankhaus Reuschel & Co.
Recognising that her wealth is sometimes a problem, she often worked incognito under the name Susanne Kant.
On her father's death she inherited his 50.1% stake in pharmaceutical and chemicals manufacturer Altana. She sits on Altana's supervisory board and helped transform it into a world-class corporation in the German DAX list of 30 top companies. In 2006 Altana AG sold its pharmaceutical activities to Nycomed for €4.5 billion, leaving only its speciality chemicals business. The €4.5 billion was distributed to shareholders as a dividend. Altana maintained its stock exchange listing and Klatten remained its majority shareholder. In 2009, she bought almost all shares she did not already own in Altana.
Her father also left her a 12.50% stake in BMW. She was appointed to the supervisory board of BMW with her brother Stefan Quandt in 1997.
German graphite maker SGL Carbon said on 16 March 2009 that Klatten owns options to raise her stake in SGL from 8% to almost a quarter of the shares but no more than that.
The Hanns Joachim Friedrichs Award winning documentary film The Silence of the Quandts by the German public broadcaster ARD described in October 2007 the role of the Quandt family businesses during the Second World War. The family's Nazi past was not well known, but the documentary film revealed this to a wide audience and confronted the Quandts about the use of slave labourers in the family's factories during World War II. As a result, five days after the showing, four family members announced, on behalf of the entire Quandt family, their intention to fund a research project in which a historian will examine the family's activities during Adolf Hitler's dictatorship. The independent 1,200-page study that was released in 2011 concluded: "The Quandts were linked inseparably with the crimes of the Nazis"-Joachim Scholtyseck, the Bonn historian who compiled and researched the study. As of 2008 no compensation, apology or even memorial at the site of one of their factories, have been permitted. BMW was not implicated in the report.
Police prevented an attempt to kidnap her and her mother Johanna Quandt in 1978.
Susanne met Jan Klatten while she was doing an internship with BMW in Regensburg, where he worked as an engineer. It is reported that during this time she called herself Kant and did not tell him who she was until they were sure about each other, but Klatten herself denies the story. They married in 1990 in Kitzbühel and live in Munich. They have three children. She plays golf and skis in Austria. She has been a member of the University Council of the Technical University of Munich since 2005. In 2007 she was awarded the Bayerischer Verdienstorden, the Bavarian Order of Merit. She is one of the biggest donors of the centre-right political party, the Christian Democratic Union.
In 2007 Klatten was blackmailed by Helg "Russak" Sgarbi, a 44-year-old Swiss national who threatened to release materials depicting the two having an affair. Sgarbi, who was charged with similar blackmail schemes against multiple women, was arrested in January 2009 and brought to court in Germany, where he was sentenced to six years in jail. His accomplice, the Italian hotel owner Ernano Barretta who allegedly filmed Sgarbi and Klatten with hidden cameras, was also arrested and was sentenced in 2012 to seven years in prison.
