In 1886, a young Irish immigrant named Margaret Tobin arrived in Leadville, Colorado—a rough mining town perched at 10,000 feet in the Rockies
You are a Denver Public Library archivist in 1932, tasked with investigating the hidden fortune of Margaret 'Molly' Brown, who died that year.
You arrive in Leadville, Colorado
Follow the traces of Margaret 'Molly' Brown, the unsinkable Titanic heroine, through Leadville's silver mines where she built her fortune before 1912.
Leadville was born in 1877 from Horace Austin Warner Tabor's vision, a prospector turned senator who transformed a mining camp into a 40,000-inhabitant metropolis in three years. The Healy House, built in 1878 by August R. Meyer as a miners' boarding house, welcomed the first gold seekers before silver veins were discovered. Nearby, the 1879 Dexter Cabin, built by silver magnate James V. Dexter, became the town's first clapboard structure. These two buildings at 912 Harrison Avenue showcase the Victorian architecture that emerged during the 1880s silver rush.
The Tabor Opera House, erected in 1879 for $45,000 by Horace Tabor, marked Leadville's cultural peak with 800 seats and programming worthy of Eastern metropolises. The first permanent opera west of the Mississippi, it hosted Oscar Wilde in 1882 during his American tour. Margaret Brown and her husband J.J. attended these society evenings, she who would become famous in 1912 organizing rescue efforts during the Titanic disaster. The opera closed in 1893 after silver prices collapsed, but reopened in 1932 as a historic monument, the year Molly Brown died.
The Delaware Hotel, built between 1883-1884 in Second Empire style, bears the name of Tabor's Delaware Mine. Its 47 rooms housed Leadville's mining elite, including the Browns who invested in local mines around 1880-1890. Harrison Avenue, the main artery paved in 1880, concentrated silver-born fortunes along one kilometer. This avenue, designated a National Historic Landmark in 1967, preserves its intact Victorian setting witnessing the boom that brought Leadville's population to its 1880 peak of 40,000.
St. George's Episcopal Church, consecrated in 1885, raised its stained glass windows imported from England for Leadville's Protestant elite, while Annunciation Church, completed in 1886, elevated its 150-foot Gothic spire for 1,500 Catholic parishioners, mostly Irish like the Browns. These two churches, financed by silver fortunes, illustrate the religious diversity of a cosmopolitan city where European miners mingled with American magnates. Leadville City Hall, built in 1903-1904 in Beaux-Arts style, testifies to the city's resilience after the 1893 crisis.
Your investigation leads to the sources of Brown fortune: the mines that transformed J.J. Brown, a simple Irish engineer who arrived in 1880, into a millionaire through discovering new veins in the Little Jonny Mine. Margaret, wife and mother, climbed Leadville's social ladder before conquering Denver then New York, until that April 15, 1912 when the Titanic sank and revealed her courage to the world. Walking these sites from 1877 to 1904, you reconstruct the rise of a woman who embodied the American Dream, from Leadville to the North Atlantic.
