Georg Reutter (3 November 1656 – 29 August 1738) was an Austrian organist, theorbo player and composer.
Reutter was born in Vienna and became a pupil of Johann Caspar Kerll, whom he later succeeded as organist at St. Stephen's Cathedral, Vienna, in 1686. In 1695 he spent some time in Italy. He was ennobled in Rome on 8 January 1695 by Prince Sforza; unlike his son, he did not use his title. Between 1696 and 1703 Reutter was employed in the Viennese court chapel as continuo player on the theorbo. The principal Kapellmeister, Antonio Draghi, recommended him to the emperor as ‘a virtuoso player able to play many instruments’. He was married three times and was the father of 15 children, of whom two became musicians (Karl and the younger Georg). In 1700 Reutter was formally appointed court organist. In 1712 he succeeded Fux as vice-Kapellmeister and in 1715 as first Kapellmeister of the cathedral; he retained that position until 1728. He passed on the position of cathedral organist to his son Georg Reutter II in 1720. He died in Vienna.
Johann Adam Joseph Karl Georg Reutter (also Georg Reutter the Younger) (6 April 1708 – 11 March 1772) was an Austrian composer. According to Jones, in his prime he was "the single most influential musician in Vienna".
Reutter was born and died in Vienna. His father Georg Reutter (the Elder) was also a notable composer. He was the 11th of 14 children and received his early musical training from his father, assisting him as court organist.
A period of more formal instruction from Antonio Caldara ensued, leading to the composition of an oratorio in 1726 and, in 1727, his first opera for the imperial court, Archidamia. On three separate occasions during this period, Reutter applied for a position as court organist and was each time rejected by Johann Joseph Fux. At his own expense he travelled to Italy in 1730 (possibly in 1729); in February 1730 he was in Venice and in April 1730 in Rome. He returned to Vienna in autumn 1730, and early in the following year he successfully applied for a post as court composer, the formal beginning of a lifetime of service at the Habsburg court. After his father's death he became Kapellmeister of St. Stephen's Cathedral in 1738.
