Not as famous as DeBakey but I met LD Britt during my oral Board certification exam (as well as a few others but he was the only name I readily recognized).
He was a condescending ass, IMHO.
NB: funny thing is, I was talking to my ex a few days before my exam (without knowing who my examiners were going to be) and he brings up Britt by name (odd, because even though he's a trauma surgeon, he didn't train with him) and tells me what a jerk he is. My heart sank a little when I saw him on the list for my last room.
PS...don't tell him I wrote this...he might revoke my results. 😉
