I have often wondered about this man. Exactly how big of a role did Carlisle play in the Titanic's design and construction? I believe he retired in 1911, and that he had extensive involvment on the Olympic, but I am surprised that he did not go on the Titanic's maiden voyage. Does anyone have any information on what happened to Carlisle he retired? Also Carlisle was Lord Pierre's brother in law. And Thomas Andrews was Pierre's nephew. Sounds like a little nepotism to me. Did Andrews originally assist and then succeed Carlisle? Who succeeded Andrews? The most I know about Carlisle was his early invovlment, and of course, his "attempts" to have more lifeboats added.
