Dresden Tactics

I have here two tactical puzzles executed by two members of the RP Team in the ongoing Dresden Olympiad.

Could you identify the correct moves as well as the player who made those moves (for the sake of those who were not able to watch these particular games)?

Tactics #1.

Black had just played 19.Bxe5. Can you find the best move for White? And who is the player in White?

Tactics #2

Black had just played 14. . . Nd7. What's the best continuation for White? Who's White?
