I guess after the tragedy, anyone who did anything was applauded as being a hero. Like Lightholler, or Bell or many other of the ships crew, he did his job until Capt. Smith gave the everyman for himself order, and the set ran out of power. I'm interested about the marconi men but I wouldn't say he was more of a hero than anyone else. He did his job, plain and simple. Thomas Andrews who could have got into a boat and proved to be an invaluable source of information at the inquest, did nothing to get himself off the ship, he helped otherswith no regard to himself, or Ida and Isador Strauss who would not leave her husbands side.
If you think he's a hero that's fine, I guess it's really a personal thing but for me, I look at the dignity and selflessness that was shown that night for my determination.
