He was made a baron and "premier peintre de la reine" (First Painter to the Queen), and drew the last portrait ever made of Louis XVI before the king’s execution. His less formal portraits reflect his fascination with physiognomy and show an interest in expanding the range of facial expressions beyond those of official portraiture.

He was the eldest son of Empress Maria Theresa and her husband, Emperor Francis I, and was the brother of Marie Antoinette. He was thus the first ruler in the Austrian dominions of the House of Lorraine, styled Habsburg-Lorraine. Joseph was a proponent of enlightened absolutism; however, his commitment to modernizing reforms subsequently engendered significant opposition, which eventually culminated in an ultimate failure to fully implement his programmes. He has been ranked, with Catherine the Great of Russia and Frederick the Great of Prussia, as one of the three great Enlightenment monarchs. His policies are now known as Josephinism. He died with no sons and was succeeded by his younger brother, Leopold II.

Document 11: Marie Antoinette syndrome: Marie Antoinette syndrome is a sudden whitening of the hair. The event that named the syndrome was the observation that the hair of Queen Marie Antoinette of France turned stark white after her capture following the ill-fated Flight to Varennes during the French Revolution. Witnesses have alleged that Antoinette's hair suddenly turned white on three separate occasions. In the novel 'One hundred and One Dalmatians', by Dodie Smith, after the Dalmatians destroy Cruella de Vil's stock of furs, the shock renders her black hair white (and her white hair green). In Victor Hugo's novel 'Les Miserables' Jean Val-Jean's hair also goes pure white after the trauma of appearing in court in Arras. Other examples can be found in George R.R. Martin's "A Song of Ice and Fire" series, where the character Theon Greyjoy's hair turns white and brittle from extended brutal torture.

Louis Philippe d'Orléans was a cousin of Louis XVI and one of the wealthiest men in France.
