When people think of inventors, they usually think of Edison or Tesla, but history is filled with forgotten figures who shaped our everyday lives. For example, the person who created the modern zipper, or the one who developed the traffic light, rarely gets attention. Short biographies of these lesser-known inventors not only educate readers but also inspire them. This kind of content has a timeless appeal, and since it’s not saturated with competition, it can attract a steady flow of readers who search for unusual knowledge and trivia.
