Object Details

Marconi Wireless Telegraph Co. Ltd.
Description
Leyden jars were essential for storing electrical charges used by the earliest wireless radios used aboard ocean liners. Shortly after RMS Carpathia's rescue of Titanic survivors, the ship visited Boston, Massachusetts. Marconi Wireless Radio employee Harry Cheetham boarded Carpathia to service the radio, which had been damaged during the Titanic operations. He replaced these two Leyden jars. One is intact and the other is broken, but fortunately the broken one shows how the jars were constructed inside to store and relay an electrical charge. Cheetham kept these artifacts as Titanic souvenirs, and donated them to the Smithsonian in 1930.
