H.G. Wells (1866–1946) was an English writer best known for his pioneering works of science fiction, including The War of the Worlds, The Time Machine, and The Invisible Man.

Beyond fiction, he was a prolific writer of history, politics, and social commentary, advocating for socialism and global peace. His visionary ideas influenced both literature and scientific thought, making him one of the most significant authors of the 19th and 20th centuries.
