On 27 June 2008 Bill Gates left day-to-day Microsoft work to focus on the foundation, remaining chairman. Neighbouring foundation 2000 is the vehicle.

On 27 June 2008 Bill Gates left day-to-day Microsoft work to focus on the foundation, remaining chairman.

Context

Neighbouring foundation 2000 is the vehicle. Neighbouring 2014 chairman exit is later. Ballmer remained CEO.

Foundation 2000 is neighbouring. Chairman exit 2014 is later.

Bill Gates was Microsoft CEO until January 2000, chairman until February 2014, then a technical adviser until 2020, and a Gates Foundation co-chair. That is not authorship of every Windows copy, every GAVI dose, or every IRS schedule. Melinda French Gates is a different person. Bill Clinton is PER-000772, a different person. A pledge is not a coverage rate. A docket is not a personality.

Why it matters

The path is immunization investment: a completed full-time philanthropy shift is an agenda-capacity instrument. A calendar change is not a coverage rate.

Who was responsible

    He shifted his calendar. The foundation staff granted. Microsoft remained Ballmer’s day-to-day. Melinda co-chaired as a different person.

What the sources establish

Microsoft carries the official instrument or communique. Reuters records the same dated act independently.

Established: 27 June 2008 full-time foundation shift, independently reported.

Not established: that malaria ended that summer, or a unique later grant-effectiveness coefficient.

The foundation staff granted. Microsoft remained Ballmer’s day-to-day. Melinda co-chaired as a different person.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Gates leaves day-to-day Microsoft work for full-time foundation work, not a later speech about Gates leaves day-to-day Microsoft work for full-time foundation work.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He shifted his calendar. The foundation staff granted. Microsoft remained Ballmer’s day-to-day. That limit is the alternative to treating office-holding as authorship of every later series.
