Margaret Tobin Brown was not the perky, Debbie Reynolds-like character from The Unsinkable Molly Brown. In fact, she was not even known as Molly when she lived in Denver. The "Indomitable Mrs. James J. Brown" might have been a better nickname, since despite being snubbed by this city's society mavens after she moved here from Leadville with her husband -- the manager of a silver mine who found a deposit of gold that made them filthy rich -- she proceeded to launch a series of good works. And, yes, the couple also bought a gaudy mansion on Pennsylvania Street that survives today as the Molly Brown House Museum, a historic landmark. See also: Beth Malone on Molly Brown, Playing Strong Historical Characters, and Coming Back to Denver Margaret Brown pushed for safer mining conditions, pushed for public bathhouses and parks, pushed for juvenile justice and pushed for a woman's right to vote. She even ran for the state Senate. And she didn't just push in Denver: She traveled a lot -- with and without her husband (they separated in 1909).

Brown was returning from a European trip when she booked passage on the brand-new Titanic in April 1912. When that vessel hit an iceberg, she drew on her experiences in the wild, wild West to rally the passengers on her lifeboat before they were rescued by the Carpathia. When that boat arrived in New York, reporters asked how she had survived. "Typical Brown luck," she replied. "We're unsinkable."

That's when she became the Unsinkable Mrs. Brown. The Molly followed later.

And the Molly version of Brown is what lives on in the Meredith Willson musical that washed up on Broadway in 1960, became a movie starring Reynolds, and is now in previews at the Stage Theatre in the Denver Performing Arts Complex. Colorado native Beth Malone is playing the spunky, homegrown heroine.
