In the mid-19th century, electrotherapy was all the rage in medical treatments, especially for nerve-related ailments. One of the most intriguing devices from this era is the Improved Magneto-Electric Machine, a piece of medical equipment that combines early electrical science with the belief in its healing powers.
Manufactured by William Skidmore, a surgical instrument maker from Sheffield, England, the device includes inscriptions of ‘Skidmore” and “Sheffield” on the brass mechanisms. This machine is a classic example of the period’s electrotherapeutic tools, with its brass, iron, and felt components, points to its high-quality craftsmanship. Though these machines are now historical curiosities, they were once part of everyday medical practice, with many surviving examples found in museums across Australia and around the world, including the one held in the CALHN Health Museum.
How the Magneto-Electric Machine Works
At its core, the Improved Magneto-Electric Machine operates on the principles of magnetism and electricity. Inside the mahogany box is a rotating pair of coils positioned next to a fixed magnet. The user turns a crank handle to generate an electrical current. The intensity of the current can be adjusted by the speed of the crank and a knob on the side of the box, allowing the operator to control the strength of the electricity being delivered.
The machine features two brass terminals on either side of the box that can be connected to brass-handled wands, which are then applied to the patient’s body. The therapy was typically administered through the skin, where the electrical current was believed to stimulate nerves and muscles, providing relief for various conditions.
Therapeutic Uses and Instructions
The device was used for a wide range of medical complaints, particularly those involving nerve-related pain. The instructions printed on the inside of the box offer insight into how it was used:
“Connect two metallic cords or wires with the Sockets in the ends of the Box, and apply the handles connected with the other ends of the metallic cords or wires to any part of the person through which it is desirable to pass the current of Electricity.”

The instructions also suggested that the strength of the electrical current be adjusted to the patient’s tolerance, with sponges recommended to reduce discomfort. The machine was especially popular for treating conditions like toothache, neuralgia, and tic-douloureux (a painful nerve disorder affecting the face). In these cases, the operator would place one handle over the affected area while the patient held the other handle. For other parts of the body, such as the feet, one handle would be placed in water with the foot, while the other would be held in the hand.
The Rise of Electrotherapy in the Victorian Era
Electrotherapy, including the use of machines like the Improved Magneto-Electric Machine, was part of a broader trend during the Victorian era in which electricity was seen as a miracle cure. Medical practitioners believed that electrical currents could stimulate the nervous system, relieve pain, and even cure diseases. These machines were part of a larger group of therapeutic devices that were often used in private practices, clinics, and even at home. For the Victorian public, these machines represented the cutting edge of medical science and hope for healing.
Craftsmanship
One of the most striking aspects of the Improved Magneto-Electric Machine is its craftsmanship. Housed in a polished mahogany box with a brass hinged lid, the device is a beautiful example of Victorian-era industrial design. The brass components, including the coils, terminals, and crank, have an antique elegance, and the interior of the box is carefully laid out to provide a clear, detailed set of instructions for use.
Although we now know that the therapeutic benefits of the Magneto-Electric Machine probably fall into the ‘quackery’ side of medicine, the machines were ground breaking for their time; a reminder of a time when electrical currents were thought to hold the key to many medical mysteries.
