While she is perhaps best known as the former Chairman and Chief Executive Officer of Hewlett-Packard Company (HP), what is not as well known is Carly worked her way through undergraduate and graduate school. A self-made woman, she started her business career as a secretary and went on to become the first, and to date, the only woman to lead a Fortune 20 company. Carly served as the Chairman and Chief Executive Officer of Hewlett-Packard Company (HP) from 1999 to 2005, leading the reinvention of the legendary company, successfully steering it through the dot-com bust and the worst technology recession in 25 years. During her tenure, HP's revenues doubled, from $44 billion to $88 billion, with improved profitability in every product category. Today, HP is the largest technology company in the world.
