Its title, The Blue Sweater: Bridging the Gap between Rich and Poor in an Interconnected World, is drawn from a story of what appears to be unfathomable coincidence, but which Novogratz takes as a symbol of our interconnectedness with all on the planet.

As a child in the 1970s, she had given the charity Goodwill Industries an old, blue sweater. In 1987, jogging through Rwanda’s capital, Kigali, she thought she saw a boy wearing it. She was right—it still had her name on the tag. For Jacqueline Novogratz, this encounter symbolized the idea that humanity’s “collective future rests upon our embracing a vision of a single world in which we are all connected,”1 just as the blue sweater connected her, an American, with a kid in Rwanda.

The Acumen Fund, which Jacquelyn founded, is a consistently solid performer and she is both an intelligent witness and profoundly committed activist. (I've written about her as an example of the few die-hards who promoted the transition between what I call Venture Philanthropy 1.0 and Venture Philanthropy 2.0.) I'm ordering it right now and will be glad to report back when I'm done. Please feel free to join me!
