Emil Nolde was a German painter and printmaker. He was one of the first Expressionists, a member of Die Brücke, and is considered to be one of the great oil painting and watercolour painters of the 20th century. He is known for his vigorous brushwork and expressive choice of colors. Golden yellows and deep reds appear frequently in his work, giving a luminous quality to otherwise somber tones. His watercolors include vivid, brooding storm-scapes and brilliant florals.
Mata Hari was the stage name of Margaretha Geertruida "Grietje" Zelle, a Dutch exotic dancer, courtesan, and accused spy, although possibly innocent, who was executed by firing squad in France for espionage for Germany during World War I.
