Past Forward: The First Inkjet Printer Was a Medical Device

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, recording physiological signals from a patient's electrocardiogram in real time. Nine years later, Elmqvist worked with cardiac surgeon Åke Senning to develop the first fully implantable pacemaker. So whether you're running documents through an inkjet printer or living your best life due to a pacemaker, give a nod of appreciation for Dr. Elmqvist and his creative career pivot.

Abstract

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, recording physiological signals from a patient's electrocardiogram in real time. Nine years later, Elmqvist worked with cardiac surgeon Åke Senning to develop the first fully implantable pacemaker. So whether you're running documents through an inkjet printer or living your best life due to a pacemaker, give a nod of appreciation for Dr. Elmqvist and his creative career pivot.
