Well, Samuel Clemens didn't really write a large body of work that fits neatly into the science - fiction genre. 'A Connecticut Yankee in King Arthur's Court' stands out though. The protagonist's attempts to introduce modern inventions and concepts to the Arthurian era can be seen as a form of science - fictional exploration. It shows how an individual from a more advanced (in his view) time can disrupt and change a more primitive society, which is an interesting concept often explored in science - fiction.
Samuel Clemens, better known as Mark Twain, is not typically associated with pure science fiction in the modern sense. However, his work 'A Connecticut Yankee in King Arthur's Court' has some elements that could be considered proto - science - fiction.

In this story, the main character uses his modern knowledge in a medieval setting, creating a contrast between different time periods' technologies and ideas, much like what science - fiction often does with different worlds or times.
