Ivar Kreuger
Ivar Kreuger was a Swedish financier, entrepreneur and industrialist. By aggressive investments and innovative financial instruments, he built a global match and financial empire. Between the two world wars, Kreuger negotiated match monopolies with European, Central American and South American governments, and finally controlled between two thirds and three quarters of worldwide match production, becoming known as the "Match King." Kreuger's financial empire collapsed during the Great Depression.
