This slim volume is one of the primary references of most histories of locksmithing and lock making technology today. Its early history is repeated over and over in later books including its mistakes. Illustrations from this work are also reproduced over and over.
John Chubb was the son of Charles Chubb who was the brother of Jeremiah Chubb who patented the famous "dector lock" in 1818. Charles was a blacksmith and when his brother Jeremiah joined him they became the Chubb Lock Company. John became the sole proprietor of the business in 1846 upon the death of his father. The family ran the business well into the 20th century.
