Unsolved murder of Jean-Marie Leclair

Jean-Marie Leclair, also known as Jean-Marie Leclair the Elder, was a Baroque violinist and composer.
He is considered to have founded the French violin school. His brothers Jean-Marie Leclair the younger, Pierre Leclair and Jean-Benoît Leclair were also musicians.

Born in Lyon, but left to study dance and the violin in Turin. In 1716, he married Marie-Rose Casthanie, a dancer, who died about 1728.

Jean-Marie had returned to Paris in 1723, where he played at the Concert Spirituel, the main semi-public music series. His works included several sonatas for flute and basso continuo.

In 1730, Leclair married for the second time. His new wife was the engraver Louise Roussel, who prepared for printing all his works from Opus 2 onward.

Leclair was then engaged by the Princess of Orange, a fine harpsichordist and former student of Handel, and from 1738 until 1743, served three months annually at her court in Leeuwarden, working in The Hague as a private maestro di cappella for the remainder of the year.

He returned to Paris in 1743. His only opera Scylla et Glaucus was first performed in 1746 and has been revived in modern times.
From 1740 until his death in Paris, he served the Duke of Gramont, in whose private theatre at Puteaux were staged works to which Leclair is known to have contributed.

Jean-Marie was renowned as a violinist and as a composer. He successfully drew upon all of Europe's national styles. Many suites, sonatas, and concertos survive along with his opera, while some vocal works, ballets, and other stage music is lost.

In 1758, after the break-up of his second marriage, Jean-Marie purchased a small house in a dangerous Parisian neighborhood in the northern part of Le Marais near the old Temple, where he was found stabbed to death on October 23, 1764.
