Many of his works are portraits of noblemen, their children, and pets– those of the Duchess of Kent, the Duke of Devonshire, Cambridge and 6th Duke of Bedford, and the Earl of Ellesmere, to name a few. Esteemed and coveted by the aristocracy, his reputation reached the highest level of all as he became a friend of Queen Victoria and King Albert.
A man of many interests, Landseer was also a lover of the Scottish wilderness, spending much of his time hunting, fishing, and sketching. There, he created many anatomical studies on animals, always reaching for the highest level of accuracy in his art. His works commonly show not only animals, but also the relationship between animals and humans, often to communicate a moral or express social consideration.
Despite his professional and social successes, especially in the second half of his life, Landseer frequently suffered from nervous breakdowns, depression, and a myriad of phobias. Regardless of these health difficulties, Landseer continued to accept commissions. However, his patrons often found it challenging getting him to finish the works due to his tendency to procrastinate.
