Learn English – How to say ‘Already I know you’ in a formal way

politeness

I attended a seminar given by a great scholar few years back. Then I had a chance to meet him in one of my colleague family function. My friend introduced me to him. I said:

Already I know you. I have attended one of your seminar.

But I thought it was little bit rude and too straightforward.

Is there any other way to start a conversation or introduce ourselves to a famous person?

Best Answer

If you actually met and spoke with the person:

Hello, we've already met. If you recall ...

Hello, we've actually been previously introduced ...

If you've just gone to see one of his lectures:

Hello, actually I attended one of your lectures ...

Hello, I actually know you, I came to see you when you were at (A) to give a lecture on (B).

Or if it's, for example, a famous celebrity (if you don't mind being cliche):

Hello I'm (A) and of course I know who you are. I am a big fan of your work.
