Who is Albert Einstein from Surely You're Joking, Mr. Feynman! and what is their importance?

Feynman interacts with Einstein, probably the most famous scientist of the twentieth century, during his time at Princeton. As a student, Feynman is giving his first scientific talk, and is intimidated when he learns the legendary Dr. Einstein will be among the extremely famous scientists in attendance at the presentation. However, the Einstein presented here appears very supportive of the young beginning scientist, and very humble.
