William Henry Gates III (born October 28, 1955) is an American business magnate [工业巨头], software developer, and philanthropist [慈善家]. He is one of the best-known entrepreneurs and pioneers of the microcomputer revolution of the 1970s and 1980s. In October 2017, he was surpassed by Amazon founder and CEO Jeff Bezos, who had an estimated net worth of US$90.6 billion compared to Gates's net worth of US$89.9 billion at the time. As of January 2021, Gates had an estimated net worth of US$163 billion, making him the third-richest person in the world.

Gates took an interest in programming the GE system in BASIC, and he was excused from math classes to pursue his interest. He wrote his first computer program on this machine, an implementation of tic-tac-toe that allowed users to play games against the computer.

After the Mothers Club donation was exhausted, Gates and other students sought time on systems including DEC PDP minicomputers. One of these systems was a PDP-10 belonging to Computer Center Corporation (CCC) which banned for the summer Gates, Paul Allen, Ric Weiland, and Gates's best friend and first business partner Kent Evans, after it caught them exploiting bugs in the operating system to obtain free computer time.

Rather than use the system remotely via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including Fortran, Lisp, and machine language. At 17, Gates formed a venture with Allen called Traf-O-Data to make traffic counters based on the Intel 8008 processor.

Gates devised an algorithm for pancake sorting as a solution to one of a series of unsolved problems presented in a combinatorics class by professor Harry Lewis. His solution held the record as the fastest version for over 30 years, and its successor is faster by only 2%. His solution was formalized and published in collaboration with Harvard computer scientist Christos Papadimitriou.

Gates remained in contact with Paul Allen and joined him at Honeywell during the summer of 1974. In 1975, the MITS Altair 8800 was released based on the Intel 8080 CPU, and Gates and Allen saw the opportunity to start their own computer software company. Gates dropped out of Harvard that same year. His parents were supportive of him after seeing how much he wanted to start his own company.

In an interview that was held at the TED conference in March 2015, with Baidu's CEO, Robin Li, Gates said he would "highly recommend" Nick Bostrom's recent work, Superintelligence: Paths, Dangers, Strategies. In June 2019, Gates admitted that losing the mobile operating system race to Android was his biggest mistake.
