Forgive me because I'm not sure who's spoken in the past but from Eddie Adams, these were some of the people that I found really inspiring/memorable:
Eugene Richards
John H. White
Ami Vitale
Lynn Johnson
Gregory Heisler
Dan Winters
Darcy Padilla
Christopher Anderson
Emilio Morenatti
John Moore
and Adrees Latif and Jamie Wellford, though I do know they spoke last year.
I would also love to hear Don Weber, Joao Silva and Kevin Frayer
