Satoshi did.

He handed it off to Theymos quite quickly though.

Check this thread, https://bitcointalk.org/index.php?topic=881877.0. If I'm not wrong, it is Sirius and theymos.

Cool!
Thank you
I got this

This forum was created by Satoshi and Sirius. I didn't know about Bitcoin at the time.

So it was satoshi afterall
but how did theymos got hold of it when he didn't knew of bitcoin at that moment???
