Charles Herbert Lightoller, DSC & Bar, RD (1874 -- 1952) was the second officer on board the RMS Titanic and a decorated Royal Navy officer. He was the most senior member of the crew to survive the Titanic disaster.
As an officer in charge of loading passengers into lifeboats, Lightoller not only enforced with utmost strictness the "women and children first" protocol; he also effectively extended it to mean "women and children only". In pursuance of this principle, Lightoller lowered lifeboats with empty seats if there were no women or children waiting to board.
