Last week, on July 15, 1950, Arianna Huffington was born. The media giant was born in Athens to father Konstantinos and mother Elli. She was named Ariadne-Anna Stasinopoulou. In 1986 she married Michael Huffington. Shortly thereafter, in 1990, she became a United States citizen. Huffington is the co-founder, president, and editor-in-chief of the Huffington Post Media Group.

She moved to England when she was only 16 and graduated from Cambridge University with an M.A. in Economics. At 21, she became president of the famed debating society, the Cambridge Union.

In May 2005, she launched The Huffington Post, a news and blog site that quickly became one of the most widely read, frequently-cited media brands on the Internet. In 2012, the site won a Pulitzer Prize for national reporting.

She has been named to Forbes’ Most Powerful Women list and made Time Magazine’s list of the world’s 100 most influential people.

She serves on several boards, including The Center for Public Integrity; The Committee to Protect Journalists; HuffPost’s partner in Spain, the newspaper EL PAIS; Payoff; and ONEX. She is also a heavy presence in the media. In 2005 she appeared on the Daily Show with Job Stuart. She also joined the cast of Seth MacFarlane’s animated series, The Cleveland Show, playing the wife of Tim the Bear, also named Arianna.

Her 14th book, Thrive: The Third Metric to Redefining Success and Creating a Life of Well-Being, Wisdom, and Wonder debuted at #1 on the New York Times Bestseller list and was released in paperback in March. Her newest book Sleep Power, on the science, history and mystery of sleep is scheduled to be published next April.
