Richard Dawkins' most famous debate, who was the other man?

There’s on in particular that I’m thinking of and I can’t for the life of me remember the mans name.

Could you be thinking of John Lennox?

This one?

Or possibly David Quinn.

I’d really like to see him debate Robert Bakker.

Bakker sees absolutely nothing contradictory in being a very respected and possibly the most well known contemporary paleontologist as well as a pentecostal preacher. He does not mince his words concerning Dawkins (tail end of the interview).
