notes: label: Description
content: Leyden jars were essential for storing electrical charges used by the earliest wireless radios used aboard ocean liners. Shortly after RMS <i>Carpathia</i>'s rescue of <i>Titanic</i> survivors, the ship visited Boston, Massachusetts. Marconi Wireless Radio employee Harry Cheetham boarded <i>Carpathia</i> to service the radio, which had been damaged during the <i>Titanic</i> 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 <i>Titanic</i> souvenirs, and donated them to the Smithsonian in 1930.
