content: Charles F. Marvin, recently named professor of meteorology at the U.S. Weather Bureau, designed a new recording barometer in 1904. The inscription on this example reads "Compensated Barograph No. 1, Marvin System, made by Schneider Brothers, N. Y." The word “compensated” here pertains to fluctuations in the ambient temperature. The compensation is in the glass, which expands to offset the temperature effect.
