ESSA was established on 13 July 1965 under the Department of Commerce's Reorganization Plan No. 2 of 1965. Its creation brought the Weather Bureau and the Coast and Geodetic Survey, as well as the Central Radio Propagation Laboratory that had been part of the National Bureau of Standards, together under a single parent scientific agency for the first time. Although the Weather Bureau and Coast and Geodetic Survey retained their independent identities under ESSA, the offices of Director of the Weather Bureau and Director and Deputy Director of the Coast and Geodetic Survey were abolished. These offices were replaced by a new Administrator and Deputy Administrator of ESSA.
