Luigi Pichler
Luigi Pichler (January 31, 1773 in Rome – March 13, 1854 in Rome) was a German-Italian artist in engraved gems.
Son of Anton Pichler and half-brother and student of Giovanni Pichler, Luigi was an apprentice to his greatly renowned 39-year older brother and painter Domenico de Angelis.
He travelled to Vienna, where he, in 1818, was made professor of gem-engraving at the Vienna Academy of Fine Arts, and where he, working for Francis I, created replicas of some of the most famous gems in Austria as part of the "Vienna Cabinet", a gift for Pope Pius VII.
His works are almost exclusively intaglio, and he created many copies of his brother's and father's work.
In 1850 he turned back to Rome, where he died in 1854.
His works include a head of Ajax, the gods Apollo, Mars, Venus, Cupid, and Psyche, a head of Julius Cæsar; as well as two heads of Jesus.

Marguerite Louise d'Orléans
Marguerite Louise d'Orléans (28 July 1645 – 17 September 1721) was a Princess of France who became Grand Duchess of Tuscany, as the wife of Grand Duke Cosimo III de' Medici.
Libertine and unruly in conduct from an early age, her relations with her husband and his family were tempestuous and often bitter, with repeated appeals for mediation to Louis XIV.
Nevertheless, three children were born to the couple:
Grand Prince Ferdinando, Anna Maria Luisa, Electress Palatine, and Gian Gastone.
In June 1675, five years after her husband had succeeded to the Grand Duchy and four years after the birth of their youngest child, Marguerite Louise and her husband separated and she retired with a pension to a convent on the outskirts of Paris.
In France she proved little inclined to respect social conventions governing the life of a woman of her rank and proved a thorn in the side of the Tuscan authorities and the French monarchy, indulgent though it was.
In later life, she eventually adopted more conventional behaviour, took up pious works and even reformed the convent that became her second residence in the Paris suburbs.
As the years went by she suffered serious setbacks to her health and the sadness of mourning her eldest son, Grand Prince Ferdinando, for whom she had had a genuine affection.
Rendered financially independent by a legacy, she purchased a house in Paris, from which she spent the end of her life dispensing charity and keeping up dignified correspondence.
Marie Louise d’Orléans
Marie Louise d'Orléans (26 March 1662 – 12 February 1689) was Queen consort of Spain from 1679 to 1689 as the first wife of King Charles II of Spain.

In her adopted Spain, she was known as "María Luisa de Orleans".
Cosimo III de' Medici, Grand Duke of Tuscany
Cosimo III de' Medici( 14 August 1642 – 31 October 1723) was the penultimate( sixth) Medici Grand Duke of Tuscany.
He reigned from 1670 to 1723, and was the elder son of Grand Duke Ferdinando II.
Cosimo's 53- year- long reign, the longest in Tuscan history, was marked by a series of ultra-reactionary laws which regulated prostitution and banned May celebrations.
His reign also witnessed Tuscany's deterioration to previously unknown economic lows.
He was succeeded by his elder surviving son, Gian Gastone, when he died, in 1723.
He married Marguerite Louise d' Orléans, a cousin of Louis XIV.
The marriage was solemnized by proxy in the King's Chapel at the Louvre, on Sunday, 17 April 1661.
It was a marriage fraught with tribulation.
Marguerite Louise eventually abandoned Tuscany for the Convent of Montmartre.
Together, they had three children: Ferdinando in 1663, Anna Maria Luisa, Electress Palatine, in 1667, and Gian Gastone, the last Medicean ruler of Tuscany, in 1671.
In later life, he attempted to have Anna Maria Luisa recognised as the universal heiress of Tuscany, but Charles VI, Holy Roman Emperor, would not allow it because Tuscany was an imperial fief, and he felt he alone could alter the Tuscan laws of succession.
All Cosimo's efforts to salvage the plan foundered, and in 1737, upon his younger son's death, Tuscany passed to the House of Lorraine.
Jenny Zillhardt
Jenny Zillhardt or Marguerite Valentine (16 March 1857 – February 1939) was a French painter.

He is remembered today primarily as a patron of music.
An excellent musician himself (sometimes called "the Orpheus of princes"), he attracted top musicians to Florence and thus made it an important musical center.
Through his patronage of Bartolomeo Cristofori, Ferdinando made possible the invention of the piano.
