Richard Wagner was one of the most influential composers in Western music history, known for his epic operas — or "music dramas" — including the four-opera cycle Der Ring des Nibelungen, Tristan und Isolde, and Parsifal. He developed the concept of the Gesamtkunstwerk (total work of art), transforming opera by integrating music, drama, poetry, and stagecraft. His politics and antisemitism have made him deeply controversial.

Sir Arthur Conan Doyle created Sherlock Holmes — one of the most enduring fictional characters ever imagined — in A Study in Scarlet (1887).
