What was the name of the Titanic's first officer?

The Titanic's first officer was William Murdoch. His full name was William McMaster Murdoch, a Scottish sailor who had risen through the White Star Line and Royal Naval Reserve before joining Titanic's maiden voyage.

Murdoch was initially assigned the role of chief officer, but Henry Wilde joined the ship after it reached Southampton and took that senior position. Murdoch consequently served as first officer, with Charles Lightoller as second officer and the other junior officers below them in rank.

On the night of 14 April 1912, Murdoch was the senior officer of the watch when the lookouts reported an iceberg ahead. He ordered the helm turned and attempted to slow the ship, but Titanic struck the iceberg and sank early on 15 April. During the evacuation, Murdoch supervised lifeboat operations on the starboard side.

Films have sometimes portrayed Murdoch in dramatic scenes, including an alleged suicide, but there is no reliable evidence identifying him that way. Historical accounts establish his position and duties, while the precise circumstances of his death remain uncertain.
