Willem Einthoven (21 May 1860 – 29 September 1927) was a Dutch medical doctor and physiologist. He invented the first practical electrocardiograph (ECG or EKG) in 1895 [ 1 ] and received the Nobel Prize in Physiology or Medicine in 1924 for it ("for the discovery of the mechanism of the electrocardiogram").
[4] Einthoven developed a sensitive form of string galvanomter that allowed photographic recording of the impulses associated with the heartbeat. He was a leader in applying the string galvanometer to physiology and medicine, leading to today's electrocardiography. [5] Einthoven was awarded the 1924 Nobel prize in Physiology or Medicine for his ...
In 1901, Einthoven, working in Leiden, the Netherlands, used the string galvanometer: the first practical ECG. [93] This device was much more sensitive than the capillary electrometer Waller used. In 1924, Einthoven was awarded the Nobel Prize in Medicine for his pioneering work in developing the ECG.
In 1897 a French electrical engineer, Clement Ader, invented the "string galvanometer", containing a tensioned string of quartz. In 1903, Einthoven modified Ader's machine, adding electrodes attached to the patients limbs and thorax. In use the string was seen to vibrate in time with the patients heart. The vibrations were recorded ...
From 1906, he corresponded with the Dutch physiologist Willem Einthoven concerning the latter's invention of the string galvanometer and electrocardiography, and Lewis pioneered its use in clinical settings. Accordingly, Lewis is considered the "father of clinical cardiac electrophysiology".

Later, he worked with Dr. Thomas Lewis to set up the Einthoven string galvanometer. [4] He worked with Alfred Ezra Mirsky. One of his main areas of study was the quantitation and description of the activities of the human heart. [5] He made his first electrocardiogram at Mount Sinai Hospital (Manhattan). [4]
