The creation of static electricity by means of a machine like this one was essential to the conducting of experiments and public demonstrations by Franklin and his Philadelphia colleague Ebenezer Kinnersley. Philip Syng, Jr., is sometimes credited with the basic design for the electrostatic machines: he worked with Franklin and Kinnersley in electrical experimentation.
