On December 23, 1900, Reginald Fessenden made the first wireless transmission of human speech between two sets of 50-foot masts erected along the shore of Cobb Island. The message ("Hello. One, two, three, four. Is it snowing where you are Mr. Thiessen? If it is, telegraph back and let me know." was received here and was perfectly intelligible. Fessenden's and Very's helper, Alfred Thiessen immediately telegraphed back his response.
This site later became the permanent residence of Very who renamed it Villa Sans Souci as it remains today. Fessenden transmitted the historic message from Vickers' House, the large summer home of George Vickers that had been built after he acquired the entire island in 1889. Fessenden went on to pioneer many other innovations in radio technology.
