by J. Franklin (John Franklin) Reigart
Born in Lancaster, Pennsylvania, John Franklin Reigart built a varied career that reached beyond writing. A local biographical source describes him as a man of strong intellectual energy who studied civil engineering, worked on early Pennsylvania railroad projects in the 1830s, served as surveyor for Lancaster, and published the first map of the city.
He also became closely associated with the world of invention and patents. His Inventor's and Patentee's Guide and Pocket Record helped explain United States patent law and Patent Office procedure for inventors, showing how directly his writing connected to practical problems of the day.
Reigart is best known to many readers as the author of The Life of Robert Fulton (1856), a substantial biography of the steamboat pioneer, and as the author of The History of the First United States Flag. Together, those books show his lasting interest in American ingenuity, national symbols, and the people who helped shape the early United States.
