Parson Russell, an English clergyman, was passionate about hunting, especially fox hunting, and he sought to create a breed of terrier that possessed the agility, determination, and strength to work alongside hounds in the field. His efforts culminated in the establishment of the breed that would later be known as the Jack Russell Terrier.
