Co-founder of Microsoft Bill Gates steps down from the company’s board to spend more time on philanthropic activities.
He says he wants to focus on global health and sustainability, education and climate change.
One of the richest men in the world, Mr. Gates, 65, has also left Berkshire Hathaway, the board of Warren Buffett’s large investment firm.
In 2008, Mr. Gates stepped down from his regular job running Microsoft.
In announcing his new move, Mr. Gates said that the organization would “always be an integral part of the work of my life” and that it will continue to communicate with its members.
Yet he said: “I look forward to this next step as an opportunity to preserve the most significant friendships and collaborations for me, continue to contribute to two organizations of which I am extremely proud, and effectively prioritize my effort to tackle some of the toughest challenges in the world.”
Forbes ranks Mr. Gates as the second wealthiest man in the world after Amazon founder Jeff Bezos and is worth $103.6bn (£ 84.4bn).
He made his fortune designing personal computer applications
He dropped out of college as a young man and moved to Albuquerque, New Mexico, where he founded Microsoft with his childhood friend Paul Allen who died in 2018.
Their big break came in 1980 when Microsoft signed an MS-DOS agreement with IBM to construct the operating system.
Microsoft went public in 1986 and Bill Gates had become the youngest self-made billionaire within a year, at 31.
Mr. Gates has served on the board of Berkshire since 2004 but devotes much of his time with his wife, the Bill & Melinda Gates Foundation, to the charitable organization.
The pair were named in 2018 by The Chronicle of Philanthropy as the most generous philanthropists in the US, after giving their foundation $4.8bn the previous year.
