The signs of possible trouble appeared in the past week, when Jewett’s name, picture and letter (which first announced their marriage last year) vanished from the website of the Giving Pledge, a public vow by billionaires to give away half their wealth before they die.
And non-profits that received grants had typically thanked both Scott and Jewett.
Recent recipients, however, have only mentioned Scott.
He left the school after the marriage was announced, saying he felt his presence on campus would have been a distraction.
Many friends and colleagues were caught by surprise when Jewett revealed he and Scott had wed.
Friends described him to the Times as someone with “no sense of greed at all”.
