Redefining Visionaries As Heroes --Waldman

I love to watch the Biography channel on television when the lives of Edison or Einstein are featured, as opposed to the life of John Wayne. And you know what? How much do we really know about the inventors, pioneers and visionaries in our own industry like Otto Mergenthaler and, yes, even Gutenberg himself? Moreover, what do we know about the contributions of our contemporary industry visionaries like Efi Arazi, John Warnock and Chuck Geschke?
