John George "Jack" Phillips was a British sailor and the senior wireless operator aboard the Titanic during her ill-fated maiden voyage in April 1912.
On the final evening, Phillips had been exceptionally busy clearing a backlog of messages caused by a wireless breakdown. The steamship Mesaba sent an ice alert; he acknowledged it, but failed to pass it on to the bridge. Another from the nearby SS Californian was ignored altogether. However, Phillips and his assistant, Harold Bride, had already passed along two dozen ice warnings to the bridge. After they struck the iceberg, Phillips did his utmost to contact other ships for assistance. He died in the sinking.
