A Prussian Giant GrenadierFrederick William I wanted tall, handsome soldiers. He dressed them in tight, bright uniforms to distinguish them from the peasant population from which most soldiers came. He also ordered several portraits of his favorites, such as this one, from his court painter, J. C. Merk. Grenadiers (greh-nuh-DEERZ) wore the miter cap instead of an ordinary hat so that they could hurl their heavy grenades unimpeded by a broad brim.
