Born in Scotland on November 14, 1797, and later educated at Oxford, he became one of the most important geological writers of the 19th century. Rather than explaining landscapes mainly through sudden catastrophes, he argued that everyday processes such as erosion, sedimentation, and volcanic action, working over very long periods, could account for the Earth's history.
That idea was most famously presented in Principles of Geology (published in three volumes from 1830 to 1833), a work that reached a wide audience and helped reshape scientific thought. He also wrote Elements of Geology and The Geological Evidences of the Antiquity of Man, and his work is often linked with the broader acceptance of "deep time" in geology.
He was made a baronet in 1864 and remained a respected scientific figure until his death in London on February 22, 1875. He is still remembered not only for his own discoveries and arguments, but for the way his books opened geology to general readers and influenced later naturalists.
