Life

Popper was born in 1857 to a
Jewish family in
Bucharest,
Romania, son of professor Neftali Popper, a successful antiques merchant, and his wife Peppi. He studied in
Paris, gaining credentials as an engineer.
After working in Europe for several years, he took a job working on the infrastructure for the telegraph in Chile. He arrived in Argentina in 1885, where he became attracted by the possibility of gold mining in Tierra del Fuego. In 1886 he received a permit from the Argentine Government to form an exploration company to mine for gold near

. On September 7, he led an 18-man expedition that included a chief engineer, a mineralogist, a journalist and a photographer. They found gold dust on the beach of El Páramo, in

. The expedition was rigorously and strictly enforced according to military standards with heavily armed men, with Popper in direct command of everything.
During the expedition, Popper and his men were allegedly attacked by eighty Selk'nam (Ona) armed with bows. The adventurers responded by firing their
Winchester rifles, killing all but two of the Selk'nam. After the fight, Popper "posed his men in the attitude of troops repelling a charge, took a position himself astride one of the dead Indians, and then had the outfit photographed for subsequent use."
Popper succeeded in unearthing large amounts of gold and his ''Compania de Lavaderos de Oro del Sud'' realized enormous capital gains on the

. A mint built to manage the gold was adapted as a museum in 1973, ("Museum of the End of the Earth"), officially the (Territorial Museum) of Tierra del Fuego since 1979.
In Patagonia, Popper maintained dominance with his private army. He issued his own coins and stamps to symbolize his power. When the
Argentine peso lost its value in
the market crash of 1890, his gold coins were regarded as currency.
Popper vigorously fought against his enemies; he punished gold diggers and thieves according to arbitrary law. The most controversial aspect of his life was his participation in the
Selk'nam genocide
The Selk'nam genocide was the genocide of the Selk'nam people, one of three indigenous tribes populating the Tierra del Fuego in South America, from the second half of the 19th to the early 20th century. The genocide spanned a period of betwe ...
against the
native communities on
Tierra del Fuego. Sheep farmers and gold miners fought against them; the former because the Selk'nam would hunt sheep in their former territories and the latter because of conflicts over mining areas. Together with other bounty hunters, who were paid to kill the Selk'nam, Popper too sent his armed forces to manhunt them.
Popper also prepared an expedition to enforce the
Argentine claim for parts of
Antarctica.
After his sudden death in
Buenos Aires at the age of 35, his empire collapsed. The cause of his death has not been established. Contemporary American journalist John R. Spears says that he was poisoned by "men whom he had offended in the south."
