I wouldn't say no one has thought of it, Lynda. I've been considering and discussing the possibility with others for some years. It's with half an eye to such a future project that I've been gathering information on all the deck officers. It would be quite a monumental task, however, given the lack of specific research on some of these individuals - I've had to start from scratch on Harold Lowe, for example. His own son was suprised at how little investigative work had been down on HGL before Kerri Sundberg and I showed a specific interest in this area.
I wouldn't want to be seen as too proprietorial in this area, however, and would encourage any other conscientous researcher interested in authoring such a work to tackle the project.
