...is brought to you courtesy of Harvard. We tip our hats to them for making a free and searchable database with hundreds of prominent business people from last century. As they (Harvard that is) state, this was, "an effort to identify and chronicle the lives of 20th century men and women whose business leadership shaped the ways that people live, work, and interact." Well it's a great effort, and the result is a good-looking and straightforward browsable list/advanced search interface, wherein you can narrow by basic demographic factors like gender, birthplace, and education. (It's not unlike playing the Guess Who? boardgame, am I right?!) Individual-level results also include a small blurb about their business success. Oh and even better, if you ask nicely, they can apparently send you data in an Excel Spreadsheet.
