German billionaire Stefan von Holtzbrinck is the Co-Owner, Chairman and Chief Executive Officer of Verlagsgruppe Georg von Holtzbrinck Company, and has an estimated net worth of $1.05 billion as of March 2013. According to Forbes, he is the 57th richest person in Germany and 1332nd on the World's Billionaires list.

Mr. von Holtzbrinck earned his estimated net worth of $1.05 billion though his inheritance of the publishing company, which was founded in 1948. He served as the chairman since 2001 for the publishing house that includes book publishers Farrar Strauss & Grioux and St. Martins & Henry Holt. Prior to that, he worked as an assistant manager of the Kirch group in Munich between 1990 and 1992.

From 1992 to 1996, he built the division new media on the publishing group Georg von Holtzbrinck in Munich. He also served as the Managing Director of the Systhema publisher. Between 1997 and 2000, he served as Director of Electronic Publishing and Managing Director of Nature Publishing Group, an international scientific publisher for biology, medicine and physics. Recently, he served as Director of Stefan von Holtzbrinck Macmillan Limited.

Stefan von Holtzbrinck took over the company from his older half-brother Georg Dieter von Holtzbrinck in May 2001. Since then, he has served as its CEO. In 2011, net income for the publishing group was down by 40% to $90 million (70 million Euros) due to lean times in the firm. Its revenue dipped by 4% to $2.86 billion (2.14 billion Euros), which contributed to the $1 billion decline in his net worth since last year. HV Holtzbrinck Ventures is active in digital media and known to invest early in Internet businesses. In late 2012, Holtzbrinck sold its shares of daily deal website Groupon.

In 2006, Stefan and his billionaire half-sister, Monika Schoeller, bought out Dieter’s one-third share. They later sold to Dieter the financial newspaper Handelsbatt, 51% of the weekly paper Die Zeit, and other assets.

Born on May 15, 1963 in Ettlingen, Germany, he is the son of the founder of Verlagsgruppe Georg von Holtzbrinck. He studied Law and German at the Eberhard Karls University of Tubingen and the Ludwig-Maximillians University of Munich. As a lawyer, he apprenticed at Bloomsbury Publishing in London before joining the family company in 1994.
