Zul Premji's passion has been science and its use for the benefit of his fellow citizens. From a background of abject poverty in a village in Tanzania, he rose to become, progressively a laboratory technician, a medical doctor, and finally a malaria expert and professor of pathology in a public university. In his practice he observed the clash between tradition and modernization, between "the iPod and the mullahs." What he discovered is that more important than drugs and vaccines in combating widespread disease is the human spirit. Zul Premji tells his story in all its details—his family life, the obstacles of poverty and the impediments of politics, bureaucracy, and the human ego.
