content: Charles F. Marvin (1858-1943), 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. 3 / 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.
