Frederick Winslow Taylor's Lasting Effect on the Material World

French film director Laurent Cantet. He's made two feature films, both of which focus on the world of work, and the toll that work can take on our lives. His first film, made in 1999, was Human Resources. His newest film Time Out is about a middle-aged, mid-level executive who loses his job, but doesnt tell his family. The film has just been released here and has received critical acclaim.

Fred "Chico" Lager, former CEO of the Ben & Jerry's ice cream company. He joined the company in 1982, and together with Ben Cohen and Jerry Greenfield, built the company from a small ice cream parlor to a $100 million publicly held company. Lager just wrote a book, "Ben & Jerry's: The Inside Scoop" about his experiences building a successful business while upholding the founders' original philosophy of business as a catalyst for social change.

Business executive Max DePree. DePree turned his company, a once obscure office furniture manufacturer, into the "nation's most admired corporation" (according to Fortune magazine). DePree has just published his thoughts on enlightened management in a new book called, "Leadership Is An Art." Whereas most management books these days push an Attila the Hun approach, DePree's is closer to Saint Francis of Assisi.
