* Not a teacher
I think there's something wrong with 'most known' in spite of the fact that I have found few hits for 'most known' on both COCA and BNC. Could you give it a try before I tell you my opinion?
Also, I would use the present perfect (I have just checked Wikipedia and the writer is still alive). But this is just my choice.
