Stamitz was born in Deutschbrod,
Bohemia (now
Havlíčkův Brod, Czech Republic), into a family that came from Marburg (now
Maribor, Slovenia). Stamitz spent the academic year 1734–1735 at the
University of Prague. After only one year, at the likely age of seventeen he left the university to pursue a career as a violin virtuoso. His activities during the six-year period between his departure from the university in 1735 and his appointment in the German city of Mannheim around 1741, are not known in detail and historical accounts of his life contain many presumptions or approximations. He was appointed by the Mannheim court in 1741 or 1742, likely at the age of twenty-four. His engagement there most likely resulted from contacts made during the Bohemian campaign and coronation of
Charles VII of Bavaria, a close ally of the Elector
Palatine. In January 1742, Stamitz performed before the Mannheim court as part of the festivities surrounding the marriage of
Charles Theodore, who succeeded his uncle Karl Philipp as Elector Palatine less than a year later. Carl Albert, who became the Holy Roman Emperor on January 24, was among the wedding guests. Stamitz married Maria Antonia Luneborn on 1 July 1744. They had five children together,
Carl Philipp, Maria Franziska,
Anton Thadäus Nepomuk, and two children who died in infancy. Probably around the late summer of 1754, Stamitz paid a yearlong visit to Paris, perhaps at the invitation of music patron
Alexandre Le Riche de La Poupelinière with whom he stayed. His first documented public appearance there was a performance at a
Concert Spirituel on 8 September 1754 and he was well received by audiences. His Parisian success induced him to publish his
Orchestral Trios, Op. 1 (symphonies for string orchestra), and possibly other works of his by various publishers located there. He probably returned to Mannheim around the autumn of 1755, dying there in spring 1757, less than two years later, at the age of thirty-nine. The entry of his death reads: ''"30 March 1757. Buried, Jo'es Stainmiz, director of court music, so expert in his art that his equal will hardly be found. Rite provided"''. == Compositions ==
