History

Name origin and privateer past

The Island was owned in 1642 by James Neal, a privateer (a legal pirate working for the British Empire) who captured Spanish ships bearing treasure to Spain from Central America. Captured Spanish coins were cut into “cobbs” (smaller coins) and distributed to Maryland colonists, which led to the name “Cobb Island”.

World’s first human voice radio transmission

On December 23, 1900, Reginald Aubrey Fessenden sent and received the first intelligible speech by electromagnetic waves on a pair of masts 50 feet (15 m) high and 1 mile (1.6 km) apart on Cobb Island. Fessenden was using a spark transmitter with a Kintner-Brashear interrupter.

20th century and later

Robert Crain bought Cobb Island and organized the Cobb Island Development Company. In 1922 and 1923, the company constructed roads, a summer resort and a bridge to the island.
