"Augustus William of Prussia (German: August Wilhelm; 9 August 1722 – 12 June 1758) was Prince of Prussia and a younger brother and general of Frederick II.
Augustus was the second surviving son of Frederick William I and Sophia Dorothea. His older siblings included Wilhelmina (later Margravine of Bayreuth), Frederick II (later King of Prussia), Friedrike Louise (later Margravine of Ansbach) and Louisa Ulrika (later Queen of Sweden).
Augustus was favored by his father over Frederick and popular at the Prussian court. When his brother Frederick became king in 1740, Augustus became heir presumptive and moved into the Fredrick´s former residence, the Crown Prince´s Palace in Berlin. When his older sister Louisa Ulrika married the King of Sweden in 1744, she founded the Ordre de l´Harmonie, of which Augustus was one of the first recipients." - (en.wikipedia.org 01.06.2020)
