Victor is soon so captivated by natural philosophy that he neglects all other aspects of his life, including his family.

He rapidly advances, and after two years of intense labor he succeeds in uncovering the key to animating life.

The stranger, who the reader soon learns is Victor Frankenstein, begins his narration. He starts with his family background, birth, and early childhood, telling Walton about his father, Alphonse, and his mother, Caroline. Alphonse became Caroline’s protector when her father, Alphonse’s longtime friend Beaufort, died in poverty. They married two years later, and Victor was born soon after.

We are introduced to Robert Walton, a 28-year-old sea captain who is embarking on a journey to the North Pole region in order to find a passage from the Pacific to the Atlantic. He writes the letters to his sister, Mrs. Saville, in London, England. He has talked about making this expedition for six years: it has been a favorite dream of his, and he is pleased that he finally has a chance to make good on his promise to himself. Other dreams, such as becoming a poet or a playwright, have not worked out. Therefore, this vision must succeed. The writer of letters is thrilled that he will satisfy an "ardent curiosity" by setting foot on a part of the world never visited by man.
