and interrogates one of his pupils, Cecilia (nicknamed Sissy), whose father works at a circus. Because her father works with horses, Gradgrind demands the definition of a horse. When she is scolded for her inability to factually define a horse, her classmate Bitzer gives a zoological profile, and Sissy is censured for suggesting that she would carpet a floor with pictures of flowers or horses. Louisa and Thomas, two of Mr. Gradgrind's children, go after school to see the touring circus run by Mr. Sleary, only to meet their father, who orders them home. Mr. Gradgrind has three younger children: Adam Smith (after the famous theorist of laissez-faire policy), Malthus (after Rev. Thomas Malthus, who wrote An Essay on the Principle of Population, warning of the dangers of future overpopulation), and Jane. Josiah Bounderby, "a man perfectly devoid of sentiment", is revealed as Gradgrind's close friend. Bounderby is a manufacturer and mill owner who is affluent as a result of his enterprise and capital.

Sissy accepts the latter, hoping to be reunited with her father. At the Gradgrind house, Tom and Louisa befriend Sissy but they are all discontent with their strict upbringing. Amongst the mill workers, known as "the Hands", is a gloomy man named Stephen Blackpool (nicknamed "Old Stephen"): another of the story's protagonists. When introduced, he has ended his day's work and meets his close friend Rachael. On entering his house he finds that his drunken wife – who has been living away from him – has made an unwelcome return. Stephen is greatly perturbed, and visits Bounderby to ask how he can legally end his marriage and marry Rachael. Mrs. Sparsit, Mr. Bounderby's housekeeper, disapproves of Stephen's query and Bounderby explains that ending a marriage would be complex and prohibitively costly. When Stephen points out the injustice of this, Bounderby accuses him of having ideas above his
