Scottish painter. Schetky came from a cultured family: his father, Johann (1737-1824), was a German composer, and his mother, Maria, was the trumpeter Joseph Reinagle's sister. He took drawing lessons from Alexander Nasmyth and received a good education in Edinburgh before embarking on a Continental tour in 1801. After a spell as a drawing-master at the Royal Military College, Great Marlow, he was appointed Professor of Drawing at the Royal Naval College, Portsmouth, in 1811, a post he held for 25 years. He exhibited regularly at the Royal Academy between 1805 and 1872, his subjects ranging from ship portraits and royal embarkations to reconstructions of earlier sea battles of the time of Nelson. In 1820 he was made Marine Painter in Ordinary to George IV and was granted the same title by Queen Victoria in 1844.
