Plesch type tonoscillograph, London, England, 1931-1940
A tonoscillograph measures and records blood pressure. The device was invented by Jonas Plesch (1878-1957). He was a Hungarian physiologist and pathologist. This machine was used in medical health checks at the Pioneer Health Centre in Peckham, London during the 1930s. The Pioneer Health Centre took overall health and well being rather than simply disease as its focus of study. Graphs or tonoscillograms of members of the same family were kept together. They created a picture of a family’s general health.
