Born in the 1940s, Margaret's early life instilled in her a strong sense of curiosity and a drive to understand how things work. While specific details of her childhood are less publicly known, her later career suggests a natural aptitude for problem-solving and a willingness to question conventional approaches, qualities nurtured in her formative years.

Margaret started working as a graphic designer at Organon Pharmaceuticals in the late 1960s. This position exposed her to the world of pharmaceuticals and diagnostics, laying the groundwork for her future invention. She observed the lab technicians conducting pregnancy tests using test tube racks and reagents, a process that seemed cumbersome and inaccessible to the average woman.
