Women Who Power Engineering: Celebrating Makers This International Women’s Day

Every year on International Women's Day, people around the world celebrate the achievements, creativity, and contributions of women across every field. Engineering and mechanical innovation are no exception.

From pioneering inventors to modern technology leaders, women have played an important role in shaping the machines, systems, and technologies that power our world today.

For mechanical enthusiasts and makers, this day is also a reminder that curiosity, creativity, and the desire to build are universal. Engineering belongs to anyone who loves understanding how things work.

In honor of this global celebration, let’s look at a few inspiring women who helped move engineering and innovation forward.

Emily Warren Roebling – A Bridge Builder Against All Odds

One of the most remarkable engineering stories in history involves Emily Warren Roebling.

She played a critical role in completing the iconic Brooklyn Bridge in New York during the 19th century. When the bridge’s chief engineer, her husband Washington Roebling, became seriously ill during construction, Emily stepped in to help manage the project.

Determined to ensure the bridge would be completed, she studied advanced engineering concepts including structural analysis, materials strength, and cable construction. She became the primary liaison between engineers, contractors, and city officials.

Thanks to her dedication and leadership, the Brooklyn Bridge was successfully completed in 1883 and remains one of the most famous engineering landmarks in the world.

Her story is a powerful reminder that passion and determination can overcome even the most unexpected challenges.

Margaret E. Knight – The Woman Behind a Machine Used Worldwide

Another influential figure in engineering history is Margaret E. Knight, often called one of the most important female inventors of the 19th century.

While working in a paper bag factory, she noticed that existing bags were narrow and unstable, making them impractical for many uses. She designed and built a mechanical machine capable of producing flat-bottom paper bags automatically.

This invention revolutionized packaging and retail. The flat-bottom bag design remains widely used around the world today.

Margaret Knight held more than twenty patents throughout her lifetime, covering inventions in mechanical design, manufacturing equipment, and industrial tools. Her work demonstrates how observation and hands-on experimentation can lead to innovations that change everyday life.

Limor Fried – Empowering the Global Maker Community

Modern engineering is not only about large industrial projects—it is also about empowering individuals to explore technology through hands-on learning.

This philosophy is embodied by Limor Fried, founder of Adafruit Industries, a leading open-source electronics company that supports DIY electronics and engineering education.

Through accessible tutorials, hardware kits, and community-driven learning, Fried has helped thousands of makers, students, and hobbyists around the world learn electronics and engineering skills.

Her work highlights the growing importance of the maker movement—where curiosity, experimentation, and building things by hand play a central role in learning and innovation.

Engineering Is for Everyone

These stories span more than a century, yet they share a common theme: engineering thrives wherever curiosity exists.

Whether designing massive bridges, inventing new machines, or teaching people how to build electronics at home, innovation often begins with a simple question:

How does this work?

For many enthusiasts today, building mechanical models or engine kits is one of the most engaging ways to explore that question. By assembling real moving parts—crankshafts, pistons, flywheels, and gears—makers gain a deeper appreciation for the elegance of mechanical design.

Hands-on projects transform complex engineering principles into something tangible and rewarding.

Discover the Joy of Building

At Enginediyhop, we believe that the beauty of engineering lies in understanding how machines come to life.

DIY engine kits allow builders to:

• Explore real mechanical structures

• Learn how classic engines operate

• Experience the satisfaction of assembling a working machine from individual parts

From historic engine designs to modern precision models, these projects offer a unique way to connect with the world of mechanical engineering.

Whether you are an experienced builder, a student exploring STEM, or someone discovering the maker hobby for the first time, building an engine is an unforgettable experience.

Celebrating Makers Everywhere

This International Women's Day, we celebrate the innovators, engineers, inventors, and makers who continue to push technology forward.

Engineering has never belonged to just one group of people. It belongs to anyone curious enough to explore, build, and understand the machines that shape our world.

So whether you're assembling your first engine model or adding another masterpiece to your collection, remember that every build is part of a long tradition of curiosity-driven innovation.

And that spirit of discovery is something worth celebrating.
