Mark Cowley Lidwill (1878-1969) was a medical pioneer in anaesthesiology and cardiology. Supported by physicist Edgar H. Booth, he invented the pacemaker . [ 1 ]
The specific name honours the Australian anesthesiologist and cardiologist Mark C. Lidwill (1878–1969), who was co-inventor of the pacemaker, as well as being a saltwater angler who, while fishing for game fish, observed this tiny goby and brought it to the attention of Allan Riverstone McCulloch who subsequently described it.

A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .
Pacemakers are also sometimes used to regulate the heartbeats in people with congenital heart disease, a group of conditions that affect about 1% of people born in the U.S., ...
In 1926, the first artificial pacemaker was made by Australian physician Dr. Mark C. Lidwell. This portable machine was plugged into a lighting point. One pole was applied to a skin pad soaked with strong salt solution, while the other consisted of a needle insulated up to the point and was plunged into the appropriate cardiac chamber and the ...
Albert Salisbury Hyman (1893 - 1972), a Harvard-trained New York cardiologist, together with his brother Charles, constructed in 1930-1932 an electromechanical device which was one of the earliest artificial pacemakers. The device was reportedly tested on experiment animals and at least one human patient.
In 1971 Telectronics commenced testing samples of a new type of energy source for pacemakers, the lithium cell (lithium battery) being developed by Wilson Greatbatch and in 1972 commenced development of a range of integrated circuits capable of operation from the 2.8 volts of the cell while providing a stimulating pulse of 4.5 volts.
