Elizabeth Holmes

Elizabeth Anne Holmes is an American biotechnology entrepreneur who was convicted of fraud in connection with her blood-testing company, Theranos. The company's valuation soared after it claimed to have revolutionized blood testing by developing methods that needed only very small volumes of blood, such as from a fingerprick. 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.
