Bruce Sinclair Gustavus A. Hyde, Case Institute of Technology Professor Espy's volunteers, Cleveland, Ohio and the development ol systematic weather observation

In December 1842, James P. Espy, meteorologist, some- time professor of mathematics for the U. S. Navy but better known as the "Storm King" for his theories on the cause of storms, issued a public call for volunteer weather observers. Addressed to the "Friends of Science," via the medium of newspapers throughout the country, Espy requested all those interested in weather phenom- ena to record meteorological data in their own localities and send him the information for use in testing his weather theories.1 One of the readers of Professor Espy's circular was Gustavus A. Hyde, a seventeen year old student at the Framingham, Massachusetts Academy. Fired with en- thusiasm for the new project "I wrote to him," Hyde later recalled, "and in return received blank slips on which to take my readings."2 He purchased a ther- mometer and together with a barn weather vane and a home-made rain gauge he began making a record of the weather. Hyde's zeal lasted for well over half a century, a record perhaps unmatched by any of the other volunteers who answered the call for their serv- ices. During the period of Hyde's career, advanced from the empirical compilation of amateur observations to a science, based on the interpretation of data systematically collected by professional meteor- ologists. Gustavus A. Hyde Espy's call for volunteers came at a time of particular interest in weather. His own theory of storms was in sharp conflict with that of William Redfield, another was triumphantly received in France.

For over fifty years he faithfully re- corded Cleveland weather and each month sent a report of his observations to Washington. When compiled with the observations from a wide number of sources, the work of any one volunteer lost its identity. In Washington, Hyde was important simply as one of many who forwarded his findings. But the total effect of individual reports was considerable. Of particular significance was Espy's development of the synoptic weather chart.15 By reducing the raw data of his observers to symbols which would show wind direc- tion and force, precipitation, temperature, and baro- "A portable anemometer for registering the velocity of the metric pressure, Espy could plot the weather on a map. wind in miles and furlongs. . . .
