Bill Gates’ Early Life
Seattle Beginnings
Born to William H. Gates Sr., an attorney, and Mary Maxwell Gates, a businesswoman, Bill Gates grew up in an upper-middle-class family. At Lakeside School, he discovered computers at age 13, coding on a General Electric machine. His early passion for programming set the stage for his tech career.
Education and Early Ventures
Gates scored 1590 on his SAT and enrolled at Harvard University in 1973, studying math and computer science. He dropped out in 1975 to pursue Microsoft with childhood friend Paul Allen. Their first venture, a traffic data analyzer called Traf-O-Data, taught Gates valuable business lessons despite its initial failure.
Bill Gates’ Career Growth
Founding Microsoft
In 1975, Bill Gates and Paul Allen launched Microsoft, inspired by the Altair 8800 computer. They developed BASIC software, securing a deal with MITS. By 1981, Microsoft’s MS-DOS powered IBM’s first PC, and Windows, launched in 1985, made Gates a billionaire by age 31. Microsoft’s revenue hit $140 billion by 2000.
Global Tech Dominance
As CEO until 2000 and chairman until 2014, Gates grew Microsoft into a tech giant. Windows and Microsoft Office dominated the 1990s, with a 90% market share in PC operating systems. His strategic acquisitions, like LinkedIn in 2016 for $26.2 billion, solidified Microsoft’s innovation leadership.

Struggles and Down Phases
Antitrust Battles
In 1998, the U.S. filed an antitrust lawsuit against Microsoft, accusing it of monopolistic practices. The 2000 ruling to split the company, later overturned, damaged Gates’ reputation. Additionally, early Microsoft products like Windows 1.0 faced criticism for bugs, challenging his technical vision.
Personal and Public Scrutiny
Gates’ 2021 divorce from Melinda French Gates after 27 years sparked media attention, with allegations of workplace misconduct surfacing. The 2020 COVID-19 pandemic brought criticism of his vaccine advocacy, with conspiracy theories targeting his philanthropy. Moreover, stepping down as Microsoft CEO in 2000 was a personal low point.
Comeback and Rise to Fame
Gates’ comeback began with the Bill & Melinda Gates Foundation, launched in 2000. His shift to philanthropy, donating $59 billion by 2025, earned global respect. Named Time’s Person of the Year in 2005 alongside Melinda and Bono, he redefined his legacy from tech titan to humanitarian leader.
