In page Karel Čapek:

"

He is known as a science-fiction author who wrote before science fiction became widely recognized as a separate genre. Many of his works also discuss ethical aspects of industrial inventions and processes already anticipated in the first half of the 20th century. These include mass production, nuclear weapons and intelligent artificial beings such as robots or androids. His most productive years were during the First Republic of Czechoslovakia (1918–1938).[citation needed]
