125 Years Later, Cobb Island Honors Birthplace Of Wireless Voice Communication (Maryland)

On a quiet shoreline in Southern Maryland, a simple sentence made history — and the world hasn’t stopped talking since. Now, 125 years later, Cobb Island invites you to stand where it all began and witness the moment that launched the wireless age.

On Tuesday, Dec. 23, 2025, the Charles County Amateur Radio Club (CCARC) will host a public celebration commemorating the 125th anniversary of the first successful wireless transmission of the human voice, conducted by Canadian inventor Reginald Fessenden on Cobb Island in 1900.

The event, held at Fisherman’s Field at Cobb Island Road and Neale Sound Drive, will run from 10 a.m. to 2 p.m. and is free to attend. Visitors of all ages are encouraged to explore interactive exhibits, join live radio demonstrations, and experience a reenactment of the groundbreaking transmission.

It was on Cobb Island, on Dec. 23, 1900, that Canadian inventor Reginald Fessenden, working on behalf of the U.S. Weather Bureau, accomplished what was then believed to be impossible: he successfully transmitted a brief, intelligible voice message over the air from a transmitter site on the island to a receiver nearly a mile away. His message, reportedly “One, two, three, four. Is it snowing where you are, Mr. Thiessen?” marked the first known instance of radiotelephony and laid the foundation for modern AM broadcasting.
