Can you imagine a time when weather forecasts were not available, or when people did not know that storms followed predictable paths? The science of meteorology was in its infancy when the Smithsonian was founded in 1846, but over the next three decades, the Institution developed a national network for collecting meteorological data, and made possible some of the earliest weather forecasts.
When Joseph Henry became the Smithsonian's first Secretary in 1846, he brought with him a longstanding interest in meteorology. In the 1820s, as a professor at the Albany Academy in New York, he had proofed data sent in by weather observers throughout the state. During his time at Princeton University in the 1830s and 1840s, Henry continued to stay abreast of meteorological research.
THE PROBLEM OF AMERICAN STORMS
THE METEOROLOGICAL PROJECT
By 1859, the logs of daily observations that the Smithsonian's weather observers mailed to the Institution every month had created a massive backlog of data. Henry hired Professor James H. Coffin of Lafayette College to reduce the raw data, and Coffin employed "from twelve to fifteen persons, many of them female," as "computers" to process the data, but they struggled to keep up with the large amount of work.2 Henry himself struggled to answer the many questions raised by observers in the correspondence that frequently accompanied their registers. "Letters are often received asking for information on meteorological and other subjects. These embrace a very wide range of inquiry, and, with the other letters received, make large demands on the time of the secretary," Henry wrote in his annual report for 1859.3 Some observers expressed annoyance that the data they had loyally provided for years was not being published, while others requested compensation in the form of Smithsonian publications. On the other hand, for observers such as Ernst Kapp, who had been an acquaintance of Karl Marx before emigrating from Germany to rural Texas, simply keeping up a correspondence with the Smithsonian was satisfactory, as it provided an opportunity for intellectual and scientific companionship.4
TRANSFERRING WEATHER OBSERVATION TO THE US GOVERNMENT
With its other obligations, by the mid-1850s the Smithsonian could not afford to operate the meteorology program on its own and enlisted the agricultural division of the Patent Office to distribute and collect weather registers, and to pay the wages of those employed to reduce data. In exchange, Joseph Henry wrote a series of lengthy essays for the Patent Commissioner's annual reports. Five installments of his "Meteorology in Its Connection with Agriculture" were published by the Patent Office, whose agricultural reports were likely read by many of the farmers who participated in the Smithsonian's observer network. After the Patent Office stopped supporting the meteorological project in 1860,5 the Agriculture Department assisted the Smithsonian with collecting data shortly after its establishment in 1862.6
From 1861 to 1865, Joseph Henry's meteorological program was severely disrupted by the Civil War. Weather data took a back seat to other important business requiring telegraph lines, and secession prevented southern observers from using the postal service7 to mail their registers. Many observers joined the war effort.8 Others wrote to say their weather instruments had been confiscated or destroyed.9 The strained finances of the Smithsonian, which depended in part on annual Congressional appropriations, made it unable to comply with observer requests10 for barometers, rain gauges, or other such items.
In 1870, Henry succeeded in transferring the weather forecasting system to an arm of the federal government—the War Department's Signal Service. The Smithsonian's meteorological network had recovered and now included more than five hundred individual observers as well as 140 Army posts. In 1874, the Signal Service took over the volunteer observer system.11 For Henry, the transfer of the meteorological project to the Army was in keeping with his long-held belief that the Smithsonian should "devote its energies to no field of research which can be as well cultivated by other means."12 The Army continued to be responsible for weather data collection and forecasting until the establishment of the US Weather Bureau, later renamed the National Weather Service, in 1891.
