In the late 19th century, a remarkable Orlov Trotter named Clever Hans captivated the equine world with his alleged ability to perform complex intellectual tasks. Owned and trained by Wilhelm von Osten—a German mathematics teacher and part-time horse trainer—Hans was said to demonstrate extraordinary cognitive skills uncommon in horses. According to von Osten, the horse could add, subtract, multiply, divide, solve fractions, tell time, read words and numbers, spell, and even comprehend spoken and written German. When prompted with questions, Hans responded by tapping his hoof to indicate his answers.
