Mark Twain [SEP] Love of science and technology
Twain was fascinated with science and scientific inquiry. He developed a close and lasting friendship with Nikola Tesla, and the two spent much time together in Tesla's laboratory. Twain patented three inventions, including an "Improvement in Adjustable and Detachable Straps for Garments" (to replace suspenders) and a history trivia game. Most commercially successful was a self-pasting scrapbook; a dried adhesive on the pages needed only to be moistened before use. Over 25,000 were sold. Twain was an early proponent of fingerprinting as a forensic technique, featuring it in a tall tale in "Life on the Mississippi" (1883) and as a central plot element in the novel "Pudd'nhead Wilson" (1894).
