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 photograph was taken by the chief steward of the liner Prinz Adalbert on the morning of April 15, 1912. The Titanic, which struck an iceberg at 11.40 p.m. ship's time on April 14, sank just over two hours later with the loss of more than 1,500 lives. The crew of the Hamburg America Line liner was unaware of the terrible event when they saw the iceberg, according to the document.
