- After he was appointed Secretary of the Smithsonian Institution, Joseph Henry's first major project was to create the Smithsonian Meteorological Project by using a country wide network of voluntary observers to record weather information and send it to the Smithsonian. Observations were sent to the Smithsonian primarily on a monthly basis through the mails, but some observers used the growing telegraph network for more rapid transmission of the information. The Smithsonian Meteorological Project existed from 1846-1870 and led to the founding of the National Weather Service. Joseph Henry's research in electromagnetism was instrumental in the development of the telegraph and he was interested in using this new form of data transmission to record scientific information.
