Calvin and Hobbes is a syndicated daily comic strip written and illustrated by American cartoonist Bill Watterson, and syndicated from November 18, 1985 to December 31, 1995. It follows the humorous antics of Calvin, a highly precocious and adventurous six-year-old boy, and Hobbes, his sardonic stuffed tiger. The pair are named after John Calvin, a 16th-century French Reformation theologian, and Thomas Hobbes, a 17th-century English political philosopher.
While staying in Grantville, young William Cavendish found a collection of Calvin and Hobbes strips. Cavendish was impressed by what he saw, especially that the character Hobbes was named for Cavendish's tutor, Thomas Hobbes. Cavendish decided to show the book to Thomas Hobbes, but his tutor was too busy researching at the public library. After Cavendish went back to England, he used the tiger Hobbes as a secret insignia for his letters to Thomas Hobbes in Grantville.
