Portrait of Sir Charles Lyell - Pioneer of Modern Geology #3013814 (License: Personal Use)

This engraved portrait depicts Sir Charles Lyell (1797-1875), the Scottish geologist whose work established uniformitarianism as the foundation of modern geology. Dressed formally in a dark suit with waistcoat and bow tie, his contemplative gaze reflects his intellectual rigor and influence on Darwin and the scientific community. The fine-line engraving style suggests it was published in a late 19th-century biography or scientific journal.
