Henri Desmarets  (February 1661 – 7 September 1741) was a French composer of the Baroque period primarily known for his stage works, although he also composed sacred music as well as secular cantatas, songs and instrumental works.
Early years and first successes 
Henri Desmarets was born into a modest Paris household in February 1661. His mother, Madeleine née Frottier, came from a bourgeois Parisian family. His father, Hugues Desmarets was a huissier in the cavalry at the Grand Châtelet. Desmarets' childhood was marked by his father's death when he was eight years old, his mother's subsequent re-marriage in 1670, and the death of his two siblings. In 1674, he entered into the service of King Louis XIV as a page and choir singer in the Chapelle Royale (Chapel Royal). According to Duron and Ferraton, he may have also previously sung as a choir boy in Saint-Germain l'Auxerrois which was the parish church of the kings of France. While in the service of the king, he received a general education as well as music training from Pierre Robert and Henry Du Mont. He is also thought to have received training from the court composer Jean-Baptiste Lully, who used the chapel pages as performers in his operas. By 1680 he had become an "ordinaire de la musique du roi" (court musician) and had composed the first of his grand motets (Te Deum 1678). The idyll-ballet which he composed in August 1682 to celebrate the birth of the king's grandson, the Duke of Burgundy found great favour at court and the following year he entered the competition to select four maîtres (masters) of the Chapelle Royale. He was only 22 at the time and according to some accounts, the King had vetoed his selection after he had passed the first round on account of his youth.
After the competition, Desmarets petitioned the king to allow him to leave France for study with Italian composers, but Lully objected on the grounds that it would diminish his command of the French style. Desmarts remained at the court and made money by "ghost-writing" works for one of the composers who had won the competition, Nicolas Goupillet. Goupillet was dismissed from his post ten years later when the deception came to light. In the meantime, Desmarets continued to find favour with his own compositions, most notably his motet Beati quorum (1683); his divertissement, La Diane de Fontainebleau (1686) and his first full-length opera, Endymion (1686). The first performance of Endymion was in the king's private apartments at Versailles, performed in parts over six days. The Dauphine was so pleased with it that at her request it was performed again in its entirety at the court theatre ten days later. Desmarets was increasingly gravitating towards stage works, but Lully's monopoly of the Académie Royale de Musique in Paris (granted by the king) meant that operas by other composers were not presented there until after his death in 1687.
Operas on the Paris stage and scandal in Senlis 
Desmarets' Te Deum was performed in the oratory of the Louvre Palace in February 1687 to celebrate Louis XIV's recovery from illness, and later that year the king granted him a pension of 900 livres. Desmarets married Élisabeth Desprez, the daughter of a Parisian blade manufacturer, in 1689, and the following year their daughter, Élisabeth-Madeleine was born. He became the Chapel Master of the Jesuit college Louis-le-Grand in 1693 and premiered his opera Didon in June of that year. It was the first of his stage works to be performed at the Académie Royale de Musique. Over the next two years three more of his operas premiered there: Circé (1694), Théagène et Cariclée (1695), and Les amours de Momus (1695).
In the summer of 1696, Élisabeth Desmarets died, leaving him with their six year-old daughter to bring up. Desmarets became a frequent visitor to the Saint-Gobert family in Senlis, who offered to help him take care of Élisabeth-Madeleine. Both families had been friends since 1689, and Desmarets had given singing lessons to their daughter, Marie-Marguerite, when she was fifteen. During these visits, Desmarets and the now eighteen year-old Marie-Marguerite fell in love and within six months of his wife's death, they asked her father for permission to marry. He flatly refused and put his daughter in a convent when he discovered that she was pregnant. In the midst of all this, Desmarets was preparing his opera Vénus et Adonis for its 1697 premiere. The lovers eloped to Paris and Marie-Marguerite gave birth to a son in February 1698.
After the elopement, nearly three years of complicated court cases ensued with Marie-Marguerite's father, Jacques de Saint-Gobert, accusing her mother, Marie-Charlotte de Saint-Gobert, of complicity in the affair. She in turn accused her husband of attempting to poison her. Saint-Gobert disinherited his daughter and had Desmarets charged with seduction and kidnapping. Desmarets and Marie-Maguerite fled to Brussels before he could be arrested, leaving his opera Iphigénie en Tauride unfinished. He was eventually condemned to death in absentia in May 1700. With no possibility of returning to France, Desmarets took a position in Spain as the court composer to Philip V. There he and Marguerite were officially married. He left Spain in 1707 to become the master of music at the court of Leopold, Duke of Lorraine at the Château de Lunéville. (At the time, Lorraine was not officially part of France.) While he was in exile, his friends Jean-Baptiste Matho and Anne Danican Philidor kept his artistic reputation alive in France by ensuring that his works continued to be performed and published there. André Campra completed Iphigénie en Tauride for him and it premiered in Paris in 1704.
Final years 
Desmarets was finally pardoned by the French Regent in 1720, and his second marriage was officially recognized. He applied to become the master of the Chapelle Royale at the court of Louis XV in 1726, but was unsuccessful and remained in Lorraine for the rest of his days. Desmarets died in Lunéville on 7 September 1741 in his 84th year and was buried there in the convent church of the Sisters of Saint Elisabeth. Marie-Marguerite had died fourteen years earlier. Only two of their many children survived them, Francois-Antoine (1711–1786), who became a high-ranking official in Senlis and Léopold (1708-1747), who became a cavalry officer and for many years was the lover of novelist and playwright Françoise de Graffigny. Desmarets' daughter from his first marriage, Élisabeth-Madeleine, took care of him in his old age and died a few months after her father.
