Question: What city was formerly home to "Maggie", who's best remembered for exhorting the crew in Lifeboat No. 6 to return to the debris field of the 1912 sinking of RMS "Titanic" to look for survivors?

<P0-S0> Titanica is a 1992 IMAX documentary film about the RMS "Titanic". <P0-S1>  The film was directed by Stephen Low and narrated by Cedric Smith, Anatoly Sagalevich and Ralph White. <P0-S2>  The film mostly focuses on footage taken at the wreck of the RMS "Titanic", also featuring footage of the expedition crew searching the wreck as well as interviews with "Titanic" survivors Frank John William Goldsmith and Eva Hart. <P0-S3>  Using Eva and the crew members, Low conveys the voice of the documentary by showing the Titanic's wreckage as a graveyard which is to be respected and treated with caution and care. <P0-S4>  It was the second feature length IMAX film released, following "Stones at the Max" in 1991. <P0-S5>  An edited 40 minute version of the film was also later released for IMAX theatres in 1995; this version had new narration by Leonard Nimoy, though it retains most of White's narration. <P0-S6>  This edited version later became the basis for another edited version released in 1997, featuring 27 more minutes of interviews with Ralph White, Emory Kristof, and other experts. <SEP> <P1-S0>  Brown was known as "The Unsinkable Molly Brown" because she survived the sinking of the RMS "Titanic". <P1-S1>  The museum now located in her former home presents exhibits interpreting her life and that of Victorian Denver as well as architectural preservation. <P1-S2> The Molly Brown House Museum (also known as House of Lions) is a house located at 1340 Pennsylvania Street in Denver, Colorado, United States that was the home of American philanthropist, socialite, and activist Margaret Brown. <P1-S3>  The house was listed on the National Register of Historic Places in 1972. <SEP> <P2-S0> Edith Louise (Rosenbaum) Russell (June 12, 1879 – April 4, 1975) was an American fashion buyer, stylist and correspondent for "Women's Wear Daily", best remembered for surviving the 1912 sinking of the RMS "Titanic" with a music box in the shape of a pig. <P2-S1>  The paper mache toy, covered in pigskin and playing a tune known as "The Maxixe" when its tail was twisted, was used by Edith Russell to calm frightened children in the lifeboat in which she escaped. <P2-S2>  Her story became widely known in the press at the time and was later included in the best-selling account of the disaster "A Night to Remember" by Walter Lord. <P2-S3>  Russell was also portrayed in the award-winning British docudrama produced by William MacQuitty that was based on Lord's book. <SEP> <P3-S0>  She is best remembered for exhorting the crew in Lifeboat No. 6 to return to the debris field of the 1912 sinking of RMS "Titanic" to look for survivors. <P3-S1> Margaret "Maggie" Brown (née Tobin) (July 18, 1867 – October 26, 1932) (posthumously known as "The Unsinkable Molly Brown") was an American socialite and philanthropist. <P3-S2>  Accounts differ on whether the boat actually returned to look for survivors, and if so, if any survivors were found. <P3-S3>  During her lifetime, her friends called her "Maggie", but even by her death, obituaries referred to her as the "Unsinkable Mrs. Brown". <P3-S4>  The reference was further reinforced by a 1960 Broadway musical based on her life and its 1964 film adaptation which were both entitled "The Unsinkable Molly Brown".
