On this day in 1900,  Reginald Audrey Fessenden said into a microphone: “Is it snowing where you are, Mr. Thiessen? If it is, telegraph back.” His voice, radiated from a 50-foot antenna on Cobb Island in the Potomac River, Maryland, to another 50-foot antenna a mile away. The sound was rough, but Professor Thiessen heard well enough to telegraph back that it was indeed snowing. According to Harold Evans in They Made America, when Fessended asked Thomas Edison, some 20 years earlier, what he thought of the possibility  of broadcasting voices, Edison answered: “Fezzie, what do you say are man’s chances of jumping over the moon? I think one is as likely as the other.”
