" Over the past century, researchers have studied business entrepreneurs extensively..

In contrast, social entrepreneurs have received little attention. Historically, they have been cast as humanitarians or saints, and stories of their work have been passed down more in the form of children's tales than case studies. While the stories may inspire, they fail to make social entrepreneurs' methods comprehensible. One can analyze an entrepreneur, but how does one analyze a saint? "
