This intriguing piece is a Mackenzie Ink Polygraph, crafted around 1908 by Sir James Mackenzie with the assistance of Mr. Shaw, a watchmaker. This remarkable device, housed in a box measuring 10.5” x 6.5” x 4.25” tall, is a testament to early 20th-century medical and technological collaboration. Its winding mechanism still operates, spinning impressively, though the machine itself remains untested and is sold with its current contents as shown in the accompanying photos.
Despite showing signs of age with a deteriorating box, this set is considered museum-grade, reflecting its historical significance and the craftsmanship of its era. The Mackenzie Ink Polygraph was designed to record the physical manifestations of the heart and pulse, marking an important advancement in medical diagnostics.
Adding to its rich history, this polygraph was donated to the Luzerne County Medical Society by Dr. Charles H. Miner of Wilkes Barre, PA. Its provenance and functionality make it an extraordinary find for collectors, historians, and museums dedicated to preserving the evolution of medical technology. This piece not only represents a pivotal moment in the development of diagnostic tools but also serves as a beautiful example of early 20th-century innovation.
