Like his siblings, Landseer was taught artistic techniques by his father. He then studied under painter Benjamin Robert Haydon alongside his brother Charles. He began etching aged 14, copying Edwin's drawings. Thomas continued to make etched copies of Edwin's works in later life, including The Monarch of the Glen (1852) and all together he engraved 103 of Edwin’s pictures. His soft-ground etchings complimented his brother's animal paintings, and sales of the popular prints (retailing for between 3 and 10 guineas) contributed to Edwin’s fame and fortune. He assisted his brother with giving art lessons to Queen Victoria and Prince Albert.
