Bill Gates

William Henry Gates III (born 1955) co-founded Microsoft in 1975 with Paul Allen, building it into the world's dominant personal computer software company by the 1990s. He served as CEO until 2000, then transitioned to strategic roles while accumulating one of history's largest personal fortunes. In 2000, Gates and his then-wife Melinda established the Bill & Melinda Gates Foundation, which became the world's largest private charitable foundation, directing billions annually toward global health initiatives, infectious disease eradication, vaccine development, and development aid in Africa and South Asia.

Gates has become a prominent public intellectual on pandemic preparedness, climate change, and global development. His 2015 TED talk warning of pandemic risks gained renewed attention after COVID-19. He has authored books including *The Optimist's Manifesto* and *How to Avoid a Climate Disaster*, positioning himself as a techno-optimist advocate for innovation-driven solutions to existential challenges. His foundation's work on malaria, polio, and tuberculosis has influenced global health policy, though his philanthropic approach and influence over public health institutions have also drawn scrutiny and criticism from those questioning billionaire-led governance of global priorities.
