Barbara Hazel Guggenheim
Benjamin was born in Philadelphia, Pennsylvania, USA, the fifth of seven sons of the wealthy mining magnate Meyer Guggenheim (1828–1905) and Barbara Myers (1834–1900). In 1894, he married Florette Seligman (1870–1937), daughter of James Seligman, a senior partner in the firm J & W Seligman, and Rosa Seligman née Content. They had three daughters: Benita Rosalind Guggenheim (1895–1927), Marguerite "Peggy" Guggenheim (1898–1979) and Barbara Hazel Guggenheim (1903–1995).
Benjamin Guggenheim inherited a great deal of money from his father. He grew distant from his wife and for business reasons, was frequently away from their New York City home. He maintained an apartment in Paris, France.
Aboard the Titanic
Guggenheim boarded the RMS Titanic and was accompanied by his mistress, a French singer named Léontine Aubart (1887–1964); his valet, Victor Giglio (1888–1912); his chauffeur, René Pernot (1872–1912); and Madame Aubert's maid, Emma Sägesser (1887–1964). His ticket was number 17593 and cost £79 4s (other sources give the price as £56 18s 7d). He and Giglio occupied stateroom cabin B82 while Aubert and Sägesser occupied cabin B35. Pernot occupied an unknown cabin in second class.
Guggenheim and Giglio slept through the Titanic's encounter with the iceberg only to be awakened just after midnight ship's time by Aubert and Sägesser, who had felt the collision. Sägesser later quoted Giglio as saying, "Never mind, icebergs! What is an iceberg?" Guggenheim was persuaded to awaken and dress; Bedroom Steward Henry Samuel Etches helped him on with a lifebelt and a heavy sweater before sending him, Giglio, and the two ladies up to the Boat Deck.
As Aubert and Sägesser reluctantly entered Lifeboat No. 9, Guggenheim spoke to the maid in German, saying, "We will soon see each other again! It's just a repair. Tomorrow the Titanic will go on again." Realizing that the situation was much more serious than he had implied, as well as realizing he was not going to be rescued, he then returned to his cabin with Giglio and the two men changed into evening wear. The two were seen heading into the Grand staircase closing the door behind them. He was heard to remark, "We've dressed up in our best and are prepared to go down like gentlemen." He also gave a survivor a message saying, "Tell my wife, if it should happen that my secretary and I both go down, tell her I played the game out straight to the end. No woman shall be left aboard this ship because Ben Guggenheim was a coward." Guggenheim and his valet were last seen seated in deck chairs in the foyer of the Grand Staircase sipping brandy and smoking cigars. Both men went down with the ship. Their bodies, if recovered, were never identified. Guggenheim's chauffeur, René Pernot, was also lost in the disaster.
One of his final acts was to write the following message: "If anything should happen to me, tell my wife I've done my best in doing my duty." 
Benjamin Guggenheim was one of the most prominent American victims of the disaster. As such, he has been portrayed in the numerous movies, television series and a Broadway show depicting the sinking.
