Additional Information:
In 1917, the Baumanometer was developed by William A. Baum, a worker in a large clinic which engaged in pre–employment physical exams. Baum's design was the first of the sphygmomanometers which needed no adjustments or recalibration, and its well–sealed tube prevented oxidation of the mercury used for measurement. Its simplicity and striking accuracy caused it to catch on with physicians across America, and variations of Baum's simple design stand today as some of the most popular blood pressure instruments.
