Transmission type Marey sphygmograph (with tambour) by Verdin, may have belonged to Marey, belonged to Lauder Brunton, French, 1860-1904
French physiologist Étienne-Jules Marey developed this sphygmograph. Marey improved the basic sphygmograph invented by German physiologist Karl Vierordt (1818-84) in 1855 by making it portable. It is thought this instrument may have belonged to Marey himself. A sphygmograph records the pulse. It is placed on the wrist. The movement of the pulse is transmitted through the rubber diaphragm. A lever attached to the diaphragm records the pulse contraction on smoked paper.
