A string galvanometer is a sensitive fast-responding measuring instrument that uses a single fine filament of wire suspended in a strong magnetic field to measure small currents. In use, a strong light source is used to illuminate the fine filament, and the optical system magnifies the movement of the filament allowing it to be observed or ...
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 and received the Nobel Prize in Physiology or Medicine in 1924 for it ("for the discovery of the mechanism of the electrocardiogram").

Graphical representation of Einthoven's triangle. Einthoven's triangle is an imaginary formation of three limb leads in a triangle used in the electrocardiography, formed by the two shoulders and the pubis. [1] The shape forms an inverted equilateral triangle with the heart at the center. It is named after Willem Einthoven, who theorized its ...
The history section is very poorly written and misleading. For example even the date that Einthoven invented the string galvanometer is wrong. I believe the authors have simply reworked secondary publications and have not done the primary research of the dates and people involved in the early years of electrocardiography.
An early D'Arsonval galvanometer showing magnet and rotating coil. A galvanometer is an electromechanical measuring instrument for electric current.Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely.
Different organisations are responsible for awarding the individual prizes; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics; the Swedish Academy awards the Prize in Literature; the Karolinska Institute awards the Prize in Physiology or Medicine; and the Norwegian Nobel Committee awards the Prize in Peace.

Günter Blobel (German pronunciation: [ˈɡʏntɐ ˈbloːbl̩] ⓘ; May 21, 1936 – February 18, 2018) was a Silesian German and American biologist and 1999 Nobel Prize laureate in Physiology for the discovery that proteins have intrinsic signals that govern their transport and localization in the cell.
