Here's your last chance. We haven't created a list this comprehensive since 2004, when we published 50 Powerful People, and we think it's time for a revisit. Who is on your list? It could be manufacturers, inventors, technicians, producers, association members—anyone who make a difference to the business today.

Send your top three picks of the folks who make this industry tick, and tell us why. Nominations should be sent with the subject line Powerful People to editor@livedesignonline.com.
