After founding Microsoft in 1975, Bill Gates took the software industry by storm. Today, Microsoft has become one of the largest technology companies in the world—boasting a market capitalization of more than $1.6 trillion. From the Windows operating system to Microsoft Office Suite, Gates and his team forever changed the way people use computers—and ultimately planted the seeds of a global technology revolution in the process.

Gates has long been ranked as one of the world’s wealthiest men—which gave him a name recognition far greater than that of most CEOs—and businesspeople of all stripes have looked to him as a role model, using his words and business strategies to help create, inspire, and grow their own companies. After he stopped running Microsoft’s day-to-day operations in 2008 to devote himself full-time to the Bill & Melinda Gates Foundation, a kinder, gentler Gates began to emerge. In stark contrast to the implacable reputation Gates earned as a CEO, as a philanthropist, Gates has helped to change the lives of millions of people worldwide. In technology, in business, and now, in philanthropy, Gates has proven himself to be one of the most influential people of our time.
