'''James Pollard Espy''' (or '''the Storm King''') (May 9, 1785 – January 24, 1860) was a [[United States of America|U.S.]] [[meteorologist]].  Espy developed a [[atmospheric convection|convection]] theory of storms, explaining it in 1836 before the [[American Philosophical Society]] and in 1840 before the French [[Académie des Sciences]] and the British [[Royal Society]].  His theory was published in 1840 as ''The Philosophy of Storms''. He became meteorologist to the War (1842) and Navy (1848) departments and developed the use of the telegraph in assembling weather observation data by which he studied the progress of storms and laid the basis for scientific weather forecasting.
