We get to know a lot about Robert Walton via his letters to his sister. Although he is not speaking directly to the reader, we understand much about him via this method.
- He likes to write letters—which was pretty common in that time period for both men and women
- He is intelligent and well-read. Example? He quotes the Rime of the Ancient Mariner.
- He loves his sister. All of his letters are written to her and he spends a lot of time corresponding in detail.
- He seems lonely. He mentions that he is friendless.
- He is an ambitious man—he says he is traveling North to the pole and this is a brave task no one has undertaken.
- He is a good listener, as we soon find out once Victor Frankenstein arrives and launches into his life story.
