Jonathan Knight was born in Bucks County, Pennsylvania, the tenth child of Abel and Anna S. Knight. In 1801, he moved with his parents to East Bethlehem Township, Pennsylvania. He attended the common schools, worked as a teacher and purchased a farm. He continued to do survey work and became a civil engineer. He was appointed by the state in 1816 to make and report on a map of Washington County, Pennsylvania. He was elected county commissioner and served three years.

In 1828 he entered the service of the Baltimore and Ohio Railroad (B&O) to help create an engineering staff for the new company.: 14 Later that year the B&O sent him to England to study railroad engineering. Upon his return in 1830, he was appointed Chief Engineer of the B&O and served until 1842. He worked with Dr. William Howard, Lt. Col Stephen H. Long and led the design work of the B&O Main Line from Baltimore, Maryland to Harpers Ferry, West Virginia, the oldest common carrier rail line in the United States.
