In 1860, Martha J. Coston patented a pioneering maritime signaling system that utilized a unique color-coded flare system. After years of personal development and overcoming skepticism regarding its complexity and reliability, her invention gained acceptance by the U.S. Navy and other maritime organizations. Coston's system played a crucial role in enhancing nighttime communication and navigation, thereby preventing maritime accidents. Despite initial resistance, it significantly improved maritime safety and achieved wider recognition.
