About the Authors

Charles Mackay (1814-1889) was a Scottish journalist, poet and songwriter. Amsterdam merchant Joseph de la Vega – who lived in the 1600s – was a Sephardic Jewish émigré.



“Money Mania”

Desperation leads to all manner of deception, as the French learned in the 1700s, much to their chagrin. In 1716, Scottish banker John Law, a gambler and man-about-town, arrived in Paris with a scheme to save France from economic ruin. The country was reeling from debts incurred by the late, profligate King Louis XIV. A corrupt administration of courtiers and royal sycophants had left the country destitute. The Duke of Orléans – ruling as regent for the seven-year-old heir to the throne – was desperate to find a way out of the economic mess, not the least because the populace was agitating against the ruling classes.
