Original titanic vintage poster 1912 ceramic tile

The name Titanic was derived from Greek mythology and meant gigantic. Built in Belfast, Ireland, in the United Kingdom of Great Britain and Ireland (as it was then known), the RMS Titanic was the second of the three Olympic-class ocean liners—the first was the RMS Olympic and the third was the HMHS Britannic.[5] They were by far the largest vessels of the British shipping company White Star Line's fleet, which comprised 29 steamers and tenders in 1912.[6] The three ships had their genesis in a discussion in mid-1907 between the White Star Line's chairman, J. Bruce Ismay, and the American financier J. P. Morgan, who controlled the White Star Line's parent corporation, the International Mercantile Marine Co. (IMM). The White Star Line faced an increasing challenge from its main rivals Cunard, which had recently launched the Lusitania and the Mauretania—the fastest passenger ships then in service—and the German lines Hamburg America and Norddeutscher Lloyd. Ismay preferred to compete on size rather than speed and proposed to commission a new class of liners that would be larger than anything that had gone before as well as being the last word in comfort and luxury.[7] The company sought an upgrade in their fleet primarily in response to the Cunard giants but also to replace their oldest pair of passenger ships still in service, being the SS Teutonic of 1889 and SS Majestic of 1890. Teutonic was replaced by Olympic while Majestic was replaced by Titanic. Majestic would be brought back into her old spot on White Star's New York service after Titanic's loss.[8] The ships were constructed by the Belfast shipbuilders Harland and Wolff, who had a long-established relationship with the White Star Line dating back to 1867.[9] Harland and Wolff were given a great deal of latitude in designing ships for the White Star Line; the usual approach was for the latter to sketch out a general concept which the former would take away and turn into a ship design. Cost considerations were relatively low on the agenda and Harland and Wolff was authorised to spend what it needed on the ships, plus a five percent profit margin.[9] In the case of the Olympic-class ships, a cost of £3 million (£250 million in 2015 money) for the first two ships was agreed plus "extras to contract" and the usual five percent fee.[10] Harland and Wolff put their leading designers to work designing the Olympic-class vessels. The design was overseen by Lord Pirrie, a director of both Harland and Wolff and the White Star Line; naval architect Thomas Andrews, the managing director of Harland and Wolff's design department; Edward Wilding, Andrews' deputy and responsible for calculating the ship's design, stability and trim; and Alexander Carlisle, the shipyard's chief draughtsman and general manager.[11] Carlisle's responsibilities included the decorations, equipment and all general arrangements, including the implementation of an efficient lifeboat davit design.[a] On 29 July 1908, Harland and Wolff presented the drawings to J. Bruce Ismay and other White Star Line executives. Ismay approved the design and signed three "letters of agreement" two days later, authorising the start of construction.[14] At this point the first ship—which was later to become Olympic—had no name, but was referred to simply as "Number 400", as it was Harland and Wolff's four hundredth hull. Titanic was based on a revised version of the same design and was given the number
