Has Jack, Kate, Hurley or Sayid ever met Charles Widmore before?

I know this question sounds random but I ask has any of them ever met him as they travelled back in time and Sun, Ben and Locke who have met him didn't travel back in time. I know that sounds really stupid but I need to know if any of them have met him so if it is yes (one of them have met him) I can get this stupid thought out of my mind.
