Past Forward: The First Inkjet Printer was a Medical Device: Its Inventor Developed the First Implantable Pacemaker, Too

Millions of people worldwide have reason to be thankful that Swedish engineer Rune Elmqvist decided not to practice medicine. Although qualified as a doctor, he chose to invent medical equipment instead. In 1949, while working at Elema-Schonander (later Siemens-Elema), in Stockholm, he applied for a patent for the Mingograph, the first inkjet printer. Its movable nozzle deposited an electrostatically controlled jet of ink droplets on a spool of paper.
