The Bill and Melinda Gates Foundation is trying to make its work more conspicuous. That’s one explanation the billionaire couple gave for its new campus during a grand-opening event Thursday night.
About a thousand people packed into the campus' new grand atrium, which has a wall of glass four stories tall.
Bill Gates spoke briefly, thanking his parents for setting an example of civic volunteerism. He quickly turned the microphone to his wife, saying, "The person who really had responsibility was Melinda, and let me thank her as I invite her to the stage."
