Alves dos Reis

Artur Virgílio Alves Reis was a Portuguese criminal who perpetrated one of the largest frauds in history, against the Bank of Portugal in 1925, often called the Angola e Metrópole affair. At a point, he had duplicated 1% of the Portuguese GDP, leading to the collapse of the country's financial system. He was tried in May 1930, convicted and sentenced to 20 years in prison, where he converted to Protestantism. He was released in May 1945, and died of a heart attack in 1955.
