Bill and Melinda Gates
The scourge of malaria has a way of rising from the mat just when science seems to have knocked it out. Fortunately, the disease has a tenacious foe in the Bill & Melinda Gates Foundation. As the global rate of infection has crept upward again in recent years, the Gateses have committed resources to the Innovative Vector Control Consortium (IVCC), a public-private partnership devoted to developing better insecticides. The couple have also taken an increasingly impassioned stand for gender equity; independent of the foundation, Melinda is now a key financial partner in Aspect Ventures, an investment fund focused on combating sexual discrimination in tech.
