Harold Sydney Bride (11 January 1890 – 29 April 1956) was a British merchant seaman and the junior wireless operator on the ocean liner RMS Titanic during her ill-fated maiden voyage.

After the Titanic struck an iceberg at 11:40 pm 14 April 1912, Bride and his senior colleague, Jack Phillips, were responsible for relaying CQD messages to ships in the vicinity and coordinating the rescue effort which led to survivors being picked up by the RMS Carpathia.

Bride was washed off the ship as the boat deck flooded, but managed to scramble onto the upturned lifeboat Collapsible 'B', and was rescued by Carpathia later in the morning.

[2] After primary school, Bride decided he wanted to become a wireless operator and he worked in his family's business to help pay for training.

In 1912 Bride joined the crew of the RMS Titanic as the junior wireless operator and assistant to Jack Phillips at Belfast, Ireland.

During the voyage, Bride and Phillips worked from the wireless room on the Boat Deck, sending out passengers' personal messages and receiving iceberg warnings from other ships.

[1] On the evening of 14 April 1912 Bride had gone to bed early in preparation to relieve Phillips at midnight, two hours earlier than normal.

The wireless had not been working earlier and Phillips was busy catching up on a backlog of passengers' personal messages being sent to Cape Race, Newfoundland.

Captain Edward Smith soon came into the wireless room alerting Bride and Phillips to be ready to send out a distress signal.

Phillips soon returned to the wireless room reporting that the forward part of the ship was flooded and that they should put on more clothes and life vests.

Throughout the night, under Charles Lightoller's command, Bride and the others on the overturned lifeboat learned to shift their weight with swells to keep the boat afloat for as long as possible, although the collapsible was waterlogged and slowly sinking.

In the American inquiry, Bride was also questioned about ignoring requests for information, while on the Carpathia, from the press and the United States Navy, which wanted to know the fate of President Taft's personal friend and aide Archibald Butt.

Eventually, to escape the "celebrity" of being a Titanic survivor, he moved with his family to Glasgow, Scotland where he worked as a travelling salesman for a pharmaceutical company.
