Background
John Williston Cook was born on April 20, 1844 near Oneida, New York, United States. His father, Harry Dewitt Cook, decided to seek his fortune in the new state of Illinois upon learning that Congress had authorized the construction of the Illinois Central Railroad. In 1851, when John was seven, the family established a home near Bloomington, and his father engaged in the building of bridges for the railroad. When the road was completed, he became a station-master and grain-dealer. Later, he served two terms in the Assembly, was a cavalry officer in the Union army, and at the time of his death in 1873 was chairman of the State Railroad and Warehouse Commission. His various interests were not without formative influence on his son who, outside of school-hours, assisted him in his office work and accompanied him to political meetings. To the companionship of his father and the latter’s numerous acquaintances, John Williston Cook acquired the readiness of address and genial manner which were so characteristic of him in later life. His mother, Joanna Hall Cook, who had been a school-teacher, instilled in him early a love of books and study.
