How to Paint Watercolors by David Cox

David Cox, the English Watercolorist, published a book on how to paint watercolors in 1822 12 years after he was elected President of the Associated Artists of Water Colour. in 1812 he was elected an associate of the Society of Painters in Water Colour and a member the following year. He exhibited there most years until his death.

He was born in 1783 and studied drawing in his youth. He was apprenticed to a man named Fiedler in 1798 and learned to paint miniatures. He worked as an assistant scene painter in the theater from the time of Fiedler's death until 1808. After that he pursued his career as a landscape painter and drawing master.

This combination served him well in preparing his book.
