2. Explain who Valentiner was and why he found collecting Rembrandt pieces to be controversial.

Wilhelm Valentiner was born at Karlsruhe (Baden), and studied at Heidelberg under Henry Thode, and in the Netherlands with Cornelis Hofstede de Groot and with Abraham Bredius, whose assistant he was at the Gallery of The Hague.

In 1905 he was called to Berlin by William Bode, under whom he worked at the Kaiser Friedrich Museum and the Kunstgewerbemuseum Berlin. In 1906 he published his dissertation on Rembrandt that he started in 1904: Rembrandt auf der Lateinschule.
