RMS Titanic was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton, UK, to New York City, US. The sinking resulted in the loss of more than 1,500 passengers and crew, making it one of the deadliest commercial peacetime maritime disasters in modern history. The RMS Titanic, the largest ship afloat at the time it entered service, was the second of three Olympic class ocean liners operated by the White Star Line, and was built by the Harland and Wolff shipyard in Belfast with Thomas Andrews as her naval architect. Andrews was among those lost in the sinking. On her maiden voyage, she carried 2,224 passengers and crew.
Under the command of Edward Smith, the ship's passengers included some of the wealthiest people in the world, as well as hundreds of emigrants from Great Britain and Ireland, Scandinavia and elsewhere throughout Europe seeking a new life in North America. A high-power radiotelegraph transmitter was available for sending passenger "marconigrams" and for the ship's operational use. Although Titanic had advanced safety features such as watertight compartments and remotely activated watertight doors, there were not enough lifeboats to accommodate all of those aboard due to outdated maritime safety regulations. Titanic only carried enough lifeboats for 1,178 people—slightly more than half of the number on board, and one-third her total capacity.
Some of the most prominent people of the day booked a passage aboard Titanic, travelling in First Class. Among them were the American millionaire John Jacob Astor IV and his wife Madeleine Force Astor, industrialist Benjamin Guggenheim, Macy's owner Isidor Straus and his wife Ida, Denver millionairess Margaret "Molly" Brown, Sir Cosmo Duff Gordon and his wife, couturière Lucy (Lady Duff-Gordon), cricketer and businessman John Borland Thayer with his wife Marian together with their son Jack, the Countess of Rothes, author and socialite Helen Churchill Candee, journalist and social reformer William Thomas Stead, author Jacques Futrelle with his wife May, and silent film actress Dorothy Gibson, among others. Titanic's owner J. P. Morgan was scheduled to travel on the maiden voyage, but cancelled at the last minute. Also aboard the ship were the White Star Line's managing director J. Bruce Ismay and Titanic's designer Thomas Andrews, who was on board to observe any problems and assess the general performance of the new ship.
