John Hutchinson
The invention of the modern spirometer is credited to John Hutchinson of England. In 1846, Hutchinson published an article on his study conducted on 2,130 individuals to measure vital capacity. He is credited with coining the term spirometer.

In 1919, Felix Chillingworth and Ralph Hopkins on New Orleans, LA built a plethysmograph to study circulatory changes resulting from lung distention.

1920s Pulmonary Screenings at School
In France, public health officials at the beginning of the century instigated preschool and school medical examinations. The school was often the place where working class children would have their first medical evaluation. Public health stations also evaluated the children. Childhood diseases quickly spread through grade schools as infected children came in contact with other children. Ascertaining who had been vaccinated and who had the common childhood diseases became important school public health policies. An important part of the physical exam in the 1920s and 30s was measurement of lung capacity as shown here.

Scott's VC ApparatusScott's VC Apparatus
Scott's VC Apparatus
In June of 1927, Roy Wesley Scott applied for a patent for "Apparatus for Measuring the Vital Capacity of the Lungs." The patent was granted on November 18, 1930.

Scott later collaborated with the McKesson Company to produce the McKesson-Scott Vital Capacity Apparatus.

Sling Psychrometer
The psychrometer was used to measure ambient relative humidity in the pulmonary function testing lab. A wet bulb and a dry bulb thermometers were manually spun for a designated period. The temperature variation between the two thermometers was matched to a calibrated scale to determine the relative humidity.

The psychrometer, removed from the case, shows the thermometers and handle of the device. One thermometer remains dry while the sock on the second is dampened. Holding the device by the handle, the thermometers are spun repeatedly in the air. A change between the dry bulb thermometer and the wet bulb thermometers occurs. The variation in temperatures is noted on a calibration scale that correlates to relative humidity.
