Biography

Bill Gates is an American billionaire entrepreneur, software developer, philanthropist, and co-founder of Microsoft Corporation, the world’s largest software company. He was born on October 28, 1955, in Seattle, Washington, to a well-off family. His father, William H. Gates Sr., was a prominent attorney, and his mother, Mary Maxwell Gates, was a businesswoman involved in non-profit organizations and corporate boards.

Gates showed an early interest in technology and programming, writing his first computer program at the age of 13 while attending Lakeside School. In 1973, he enrolled at Harvard University, where he met Paul Allen, with whom he would later found Microsoft. Gates dropped out of Harvard in 1975 to pursue his entrepreneurial vision.

In 1975, Gates and Allen founded Microsoft, initially focusing on developing software for personal computers. Their breakthrough came in 1980, when they signed a deal with IBM to supply an operating system, which became MS-DOS. In 1985, Microsoft launched Windows, a graphical user interface that revolutionized computing and became the dominant operating system worldwide.

Under Gates' leadership, Microsoft grew into a tech giant, offering products like Office Suite, Internet Explorer, and Azure Cloud Services. Gates served as CEO until 2000, when he transitioned to Chief Software Architect and later Chairman. He stepped down from Microsoft's board in 2020 to focus on his philanthropic efforts.

In 2000, Gates and his then-wife Melinda Gates founded the Bill & Melinda Gates Foundation, which has become one of the world’s largest private charities. The foundation focuses on global health, education, and poverty alleviation, investing billions in vaccine research and disease eradication.

Gates is also a leading voice on climate change and clean energy solutions, investing in sustainable technologies through Breakthrough Energy Ventures. His philanthropic philosophy is based on using wealth to improve global living standards and tackle worldwide challenges.

As of 2025, Gates' net worth is estimated at $120 billion, making him one of the richest people in the world. He remains an influential figure in technology, philanthropy, and global policy advocacy.
