Leonhard Schulz, also known as Leonard Schulz in England (born 12 November 1813 in Vienna; died 27 April 1860 in London) was an Austrian guitarist and composer. As a guitar virtuoso, he was well known throughout Europe at the time.
Schulz was taught to play the guitar as a child by his father, Andreas Schulz (1786–1876), who worked as a guitarist in Vienna. At the age of nine, he was already performing in Vienna both as a solo artist and in a duo with his older brother, the pianist Eduard Schulz. In 1825, Schulz travelled with his father and brother to London, where they gave six concerts before the king, among others. At the age of eleven, Leonhard was already considered a ‘master of the guitar’. After a three-year stay in England, Schulz and his family returned to Vienna. This was followed by concert tours to Germany, France and again to England. Leonhard Schulz, like his brother, settled there permanently around 1830. His last known concert took place on 25 February 1841. This was followed by a decline, which, according to his brother Eduard, was due to alcoholism.
