Margaret "Molly" Brown (1867 1932) was a wealthy American lady who was travelling first class on the Titanic. She became famous for her bravery on board the ship, helping other women and children into lifeboats before her. When she was finally persuaded into a lifeboat herself, she begged that the lifeboat row back towards the Titanic to attempt to rescue more survivors, although the Quartermaster in charge of the lifeboat thought it was too dangerous. Margaret became known affectionately as "the unsinkable Molly Brown".
Wallace Hartley (1878 1912) was a violinist and the bandleader on the Titanic. He and the Titanic's orchestra of eight men continued to play throughout the Titanic disaster, calming passengers as they climbed onto the lifeboats or faced their final moments.
Joseph Bruce Ismay (1862 1937) was Chairman and Managing Director of the White Star Line, his family's shipping company, which owned the Titanic.
