The history of WWV starts fairly shortly after radio experimentation began, and also very soon after the U.S. Congress completed a mandate of the U.S. Constitution and established the National Bureau of Standards (NBS) in 1901.
The celebration this fall will recognize the issuance of call sign WWV on October 1, 1919 to the NBS, now the National Institute of Standards and Technology, NIST.
There are numerous sites which can give a more thorough and detailed history of radio station WWV than we can put together here.
NIST intends to publish a paper, preliminarily titled "A Century of WWV: 100th Anniversary Commemoration" by WWV Electronics Technician Glenn Nelson, AE0GF, just in time for the 100th celebration. We will link to the official NIST release of the paper when it becomes available.
