Giuseppe Sammartini was an Italian composer and oboist of the late Baroque and early Classical periods, born in Milan and active later in Brussels before settling in London, where he spent most of his career and served as music master to Frederick, Prince of Wales, from 1736 until his death in 1750. The brother of composer Giovanni Battista Sammartini, he was celebrated above all as a virtuoso oboist, and his compositions include chamber sonatas for recorder, oboe, and flute, concerti grossi, keyboard concertos, overtures, and trios that blend late Baroque and early galant styles.

Widely acclaimed in his lifetime as one of the greatest oboists of the age, Sammartini significantly advanced the technique and repertoire for the instrument, while his concertos and overtures helped popularize the keyboard concerto in England and eased the transition from Baroque to Classical idioms. His chamber and orchestral music remained popular through the eighteenth century, and he is remembered today as an important figure in the musical life of London during the reign of George II.
