The Sinking Of The Titanic: Returning to continuous wave spark gap transmitters; Marconi's wireless telegraphy system saved the lives of over 700 passengers aboard the Titanic which sank in April 1912. The distress calls were sent out to near-by shipping using the Marconi apparatus and were received by the Carpathia which was to effect a rescue. Marconi's work was widely credited for saving the lives of hundreds of people. The military also found a use for the wireless equipment which was used during the First World War.
