Help with the book Cannery Row?

Question

I need help if anyone knows who Doc can symbolize? I cant think of anyone he may symbolize. Thanks.

Answer 1

Doc is the father figure. Take that as far as you choose to.

Answer 2

Doc -  The proprietor of Western Biological Laboratory, a specimen supply house. Doc is a gentle, melancholy man who is a source of culture, benevolence, and aid for all on the Row. He introduces Dora's girls and the boys to opera, classical music, and literature, and he takes Frankie in and cares for him. He is also a bit of a womanizer. Somehow, though, Doc always seems lonely, and everyone on the Row is constantly wanting to do something to show him how much he is loved.
