Which Carpathia wireless operator received Titanic's distress message?

Harold Cottam was the Carpathia wireless operator who received Titanic's distress message.

Harold Thomas Cottam was the sole wireless operator aboard Carpathia during its 1912 voyage. Shortly after midnight on 15 April, he was listening for routine traffic when he contacted Titanic to offer messages received from the Cape Cod wireless station. Titanic's operator, Jack Phillips, replied with a distress call reporting that the ship had struck an iceberg.

Cottam immediately took the message and Titanic's position to the bridge. He and First Officer Horace Dean then woke Captain Arthur Rostron, who ordered Carpathia to turn around and make all possible speed. Cottam sent Titanic a message saying Carpathia was coming as quickly as possible and expected to arrive within about four hours.

He continued handling wireless traffic during the rescue, reportedly working for roughly two days with little or no sleep. Titanic's surviving operator, Harold Bride, later joined him aboard Carpathia and helped transmit information about the survivors. Jack Phillips sent Titanic's distress calls but was aboard Titanic, not Carpathia; Harold Bride was Titanic's junior operator, and Cyril Evans was operating Californian's wireless set earlier that night.
