Sir John Tenniel was a prominent British illustrator, graphic humorist, and political cartoonist active in the latter half of the 19th century. He is best remembered for his iconic illustrations for Lewis Carroll's 'Alice's Adventures in Wonderland' and 'Through the Looking-Glass.' Tenniel also served as the principal political cartoonist for the satirical magazine Punch for over 50 years, creating thousands of influential cartoons. His detailed and imaginative style left an indelible mark on Victorian art and continues to shape the popular perception of Carroll's classic works.
