Emma Lilian Todd was born in Washington, D.C., to parents of New England heritage. Growing up in a family with a strong connection to innovation and invention likely fostered her early interest in mechanics and design. Though details of her early childhood are scarce, it's clear that she developed a keen interest in how things worked from a young age.

Before dedicating herself to aviation, Lilian Todd worked as a stenographer. However, she simultaneously pursued her passion for invention. She designed and patented various inventions, showcasing her inherent inventive talent and entrepreneurial spirit. These early projects provided her with practical experience in design and manufacturing, laying the groundwork for her future endeavors in aviation.

Around the turn of the century, Todd's interests shifted towards the burgeoning field of aviation. Inspired by reports and images of early flying machines, she became captivated by the challenge of designing and building a successful aircraft. This marked a pivotal moment in her career, setting the stage for her groundbreaking contributions to aviation.

In 1906, Lilian Todd began designing her first airplane without any formal engineering training. This plane was not a kit but an entirely original design. This bold move demonstrated her confidence and determination to contribute to the field of aviation, even without conventional qualifications. Her design incorporated innovative features and was ambitious for its time.

Recognizing the importance of encouraging young people's interest in aviation, Todd founded the Junior Aero Club of America in 1908. This initiative was specifically targeted toward young boys, aiming to foster their enthusiasm for science, engineering, and aviation. Through this club, she provided educational opportunities and inspired the next generation of aviation pioneers.

In 1910, Todd's completed airplane was brought to Staten Island for its first test flight. Unfortunately, before she could fly it herself, a minor engine malfunction prevented the planned test. Though disappointing, this setback did not diminish her enthusiasm or dedication to aviation.

After the unsuccessful test flight of her first airplane, Lilian Todd largely withdrew from the field of aviation. The reasons for this decision are not entirely clear, but it may have been due to a combination of financial constraints, the competitive nature of the industry, and perhaps the prevailing societal biases against women in technical fields. The era made it difficult for an inventor to secure funding, and this was even harder for female inventors, as few were taken seriously. Her departure from aviation marked a loss for the field, as her innovative ideas and passion could have contributed significantly to its development.

E. Lilian Todd passed away on September 26, 1937, in Pasadena, California. Though she may not have achieved the widespread recognition of some of her male contemporaries in aviation, her pioneering work as a woman in a male-dominated field has earned her a place in history as a significant figure in the early development of aviation. Today, she is celebrated as a role model for women in STEM and a testament to the power of innovation and determination.
