Joseph Raphael De Lamar (1843–1918) was a Dutch-born American maritime adventurer, mining magnate, and financier who rose from poverty to amass a $29 million fortune, leaving a lasting legacy through his contributions to mining and philanthropy.
Early Life
Joseph Raphael De Lamar was born on September 2, 1843, in Amsterdam, Holland, to Maximiliaan de la Mar, a banker, and Johanna Teune. His father’s death when Joseph was four plunged the family into poverty, leaving his mother to raise seven children. As a young boy, De Lamar stowed away on a Dutch ship bound for the West Indies, working as a cook’s assistant after being discovered. This sparked a maritime career, and by age 23, he commanded a ship, gaining a global education through extensive voyages.
Maritime and Submarine Ventures
De Lamar’s early career was defined by bold ventures. He became a ship’s captain and, during the American Civil War, a submarine contractor, salvaging sunken vessels. In 1872, he raised the Charlotte, a steamship carrying Italian marble, off Bermuda, succeeding where others failed. A near-fatal incident in 1874, trapped for 36 hours in a diving suit while inspecting the Steamer William Tibbitts at Martha’s Vineyard, led him to abandon diving. He then traded along West African rivers, profiting despite significant crew losses to disease.
Mining Career
In the late 1870s, De Lamar joined the Colorado gold rush, studying chemistry and metallurgy to enhance his mining expertise. In 1879, he bought the Terrible Lead Mine in Custer County, Colorado, for $5,500, selling it in 1885 for $130,000. In Idaho, he extracted $1.5 million in gold and silver from a mountain near Silver City, selling a half-interest to the De Lamar Mining Company of England for $2 million. He invested in Colorado’s Cripple Creek and built a cyanide-process mill in Mercur, Utah, expanding it to process 1,000 tons daily. In the 1890s, he explored copper prospects in Bingham Canyon, Utah, influencing its development. His mining legacy includes ghost towns named Delamar in Nevada, Idaho, and California.
Political and Financial Career
In 1891, De Lamar served as an Idaho state senator, chairing key committees but declining a U.S. Senate candidacy. Relocating to New York, he became a secretive Wall Street financier, known as “the man of mystery” for his reserved yet successful dealings, influencing major business interests without seeking public office.
Personal Life and New York Society
In 1893, De Lamar married Nellie Virginia Sands, a John Quincy Adams descendant, and they had a daughter, Alice. After their divorce, he raised Alice alone. To cement his status in New York’s Gilded Age, he commissioned a Beaux-Arts mansion at 233 Madison Avenue, completed in 1905 with features like an automobile elevator. He also built Pembroke, a Long Island estate, housing an Aeolian organ and Tiffany stained glass. Despite his wealth, his reserved nature kept him on the fringes of elite society.
Later Years and Legacy
An accomplished organist, De Lamar hosted grand events, including Alice’s 1915 society debut. He amassed art, including sculptures and paintings, for his homes. De Lamar died on December 1, 1918, in New York from pneumonia following surgery, leaving a $29 million estate (roughly $480 million today) to Alice and $10 million to Harvard, Johns Hopkins, and Columbia for medical research. His Madison Avenue mansion, later home to the American Bible Society and National Democratic Club, became the Polish Consulate in 1973 and a New York City landmark. In 2023, De Lamar was inducted into the American Mining Hall of Fame, cementing his rags-to-riches legacy.
