- Elizabeth Holmes

Elizabeth Anne Holmes (born February 3, 1984) is an American businesswoman convicted of fraud in connection with her health technology company Theranos.[2] Holmes founded Theranos in 2003, and its valuation soared in the early 2010s after it claimed to have revolutionized blood testing by developing methods that needed only very small volumes of blood, such as from a fingerprick.[3][4] In 2015, Forbes had named Holmes the youngest and wealthiest self-made female billionaire in the United States on the basis of a $9-billion valuation of her company.[5] In the following year, as accusations of fraud about Theranos's claims began to surface, Forbes revised its estimate of Holmes's net worth to zero,[6] and Fortune named her in its feature article on "The World's 19 Most Disappointing Leaders".[7]
