The Housekeeper and The Professor - Characters

Characters

The Professor

64 years old. A former university professor who specializes in number theory. He loves mathematics, children, and the Hanshin Tigers (especially Yutaka Enatsu, who was playing for the Tigers at the time of the Professor's accident and whose uniform number was 28, the second smallest perfect number). After being in an auto accident at the age of 47, he can retain new memories for only 80 minutes. He keeps important information on notes that are attached all over his suits. He keeps baseball cards and other important mementos in a cookie tin. He has trouble interacting with other people and a habit of talking about numbers when he does not know what else to say. He has a talent for reading things backwards and finding the first star in the sky. His 80 minutes of memory eventually begins to fail, and thus he is moved to a nursing home where he spends the rest of his remaining days. But the Housekeeper, Root, and his sister-in-law continue to visit him.

The Narrator/Housekeeper

The Professor's housekeeper and a single mother. She was hired by the Professor's sister-in-law through the housekeeping agency and is the tenth housekeeper the Professor has gone through. She initially feels frustration at the Professor, who shows interest only in mathematics, but through observing the Professor's kindness and his passion for mathematics, comes to feel respect and affection for him. She first manages to connect with the Professor when he discovers that her birthday is February 20 (220), which is an amicable number with the number 284, which is imprinted on the underside of his watch, which he received as the University President's Award for a thesis he wrote in university on transcendental number theory. She cannot pronounce the title of the Journal of Mathematics (to which the Professor submits contest entries) very well, so she refers to it as "Jaanaru obu." Towards the end of the novel and at a pivotal point in the story, she and Root give the Professor a rare baseball card of Yutaka Enatsu as a congratulatory present.

Root

Ten years old. The Housekeeper's son. The Professor refers to him as "Root" on account of the top of his head being flat like a square root (√) symbol. He is the only character given something close to a name. He is an avid fan of baseball as well as the Hanshin Tigers just like the Professor, and gets the Professor to repair his old radio so that they can listen to baseball broadcasts together. His relationship with the Professor is close to that of a father and son, for the Professor is the first fatherly figure in his life. He eventually grows up to become a junior high school mathematics teacher.

The Widow/Sister-in-Law

Sister-in-law of the Professor (wife of the Professor's brother). Initially, she fired the Housekeeper for disregarding the employment contract rules (bringing her child into a client's home, staying past her assigned hours) and accused the Housekeeper's affection as an attempt to extort money from the Professor. However, after the Professor writes down Euler's formula during this confrontation, the Widow immediately comes to accept the Housekeeper and Root. She cannot walk well, which the Housekeeper later discovers was a result of her being in the same auto accident as the Professor. While browsing through the Professor's baseball card collection in the cookie tin, the Housekeeper discovers an old photograph of a younger Professor and his sister-in-law. It is hinted that perhaps long ago the Professor and his sister-in-law once had romantic feelings for each other.
