He studied at the Akademie der bildenden Künste in Vienna and then in 1767 in Paris; he was employed there by Louis-Joseph, Prince de Condé and was especially successful with his pictures of horses. In the course of his career he travelled widely, on different occasions throughout the 1770s working in England and Ireland and exhibiting his portraits and hunting pictures at the Royal Academy. In 1784 he travelled to Italy, visiting Rome and Naples, and he subsequently visited Vienna (1787), the Netherlands (1794) and Hamburg (1796); from 1797 until his death he was in St Petersburg. //
