Medici Effect: What Elephants and Epidemics Can Teach Us About Innovation . Johansson, founder and former CEO of an enterprise software company, argues that innovations occur when people see beyond their expertise and approach situations actively, with an eye toward putting available materials together in new combinations. Because of ions, "the movement of people, the convergence of science, and the leap of computation," a wide range of materials available for new, recontextualized uses is becoming a norm rather than an exception, much as the Medici family of Renaissance Italy's patronage helped develop European arts and culture. For cases in point, Johansson profiles, among others, Marcus Samuelsson, the acclaimed chef at New York's Aquavit. An Ethiopian orphan, Samuelsson was adopted by a Swedish family, with whom he traveled widely, enabling him to develop the restaurant's unique and innovative menu.
