New England billionaire Robert Kraft is continuing the work of his late wife, philanthropist Myra, by personally calling and visiting nonprofits with surprise donations.

"Once or twice a month, similar scenes are unfolding at Boston-area nonprofits, many of them small enough that a six-figure contribution is akin to hitting the lottery. The out-of-the-blue phone call or voicemail. The unlikely caller. The astonishment that leads some people to assume they’re victims of a prank. And, finally, the dawning realization that the man on the line bearing gifts is, indeed, New England Patriots owner and billionaire businessman Robert Kraft." -- Sacha Pfeiffer, the Boston Globe
