Combining art and engineering principles, he effortlessly created functional designs with an aesthetic touch.
Leonardo da Vinci’s work is inspiring because he demonstrates that innovation requires a combination of creativity, curiosity, and hands-on experimentation—qualities and skills that any budding engineer should focus on.
3. Thomas Newcomen

Similar to da Vinci, Newcomen applied his creativity and problem-solving skills to create ground-breaking innovations. His development of the first practical steam engine around the year 1712 to lift water out of the Conygree Coalworks mine in Tipton, UK was the watershed moment (literally) that kickstarted the Industrial Revolution, demonstrating that clever engineering is all about using your imagination to tackle real-world problems.
As an inventor and engineer, Newcomen’s steam engine transformed the mining industry, pumping water from mines. Unlike previous efforts, his engine produced sufficient power for consistent and reliable operation, establishing it as the industry standard for years. His partnership with ironmonger John Calley was also instrumental in constructing his steam engines, highlighting the vital role of teamwork in engineering success.
4. Charles Babbage

If you’re reading this on a computer, you can thank Charles Babbage, a brilliant mathematician and inventor born in London in 1791. While he didn’t create the computer in its current form, his ground-breaking concepts formed the foundation for modern computers. This is why he's often referred to as "the father of computing."
Babbage invented a general-purpose mechanical computer (the “Analytical Engine”) then went on to design the “Difference Engine,” a revolutionary, automatic calculator of mathematical tables. In hindsight we can recognize Babbage’s brilliance, but at the time he struggled to secure funding and buy-in for his inventions. Neither machine was fully realized in his lifetime, but his concepts influenced future generations of engineers and inventors. Resilience and determination are therefore key attributes of successful engineers.
5. Karl Benz

If you’ve driven a car today, you have Karl Benz to thank. He was the first person to build a car with a fully integrated internal combustion engine. Granted a patent in 1886, he sold the first model of his car in 1888. Although his invention was met with skepticism at the time, his ideas meaningfully formed the basis for later versions of cars and trucks.
Family and friends can play a crucial role in your career by offering support and guidance to help you achieve your goals. For Karl Benz, his wife Bertha did just that. In 1888, unknown to him at the time, she drove the Patent-Motorwagen on the first long-distance road trip and proved its reliability. Now we all know Mercedes-Benz as one of the most prestigious and reliable automotive brands in the world.
6. Alexander Graham Bell

Alexander Graham Bell is best known for inventing the telephone and transforming communications. Similar to other impressive engineers in our top 10, he didn’t just stop there. Bell also made significant advancements in the fields of aeronautics, hydrofoils, and optical telecommunications as well as founding the American Telephone and Telegraph Company (AT&T), which would go on to shape the global telecommunications landscape.
Sometimes your background can inspire your passion and lead to career success. Bell was a teacher of speech and elocution before becoming an inventor, motivated by his commitment to helping people with hearing loss, as both of his parents were actively engaged in the study of speech and hearing. His passion for sound and communication was profound, serving as the driving force behind his invention of the telephone.
7. Thomas Edison

One thing you can definitely say about Edison is that he was an optimist. He is well known for stating that he never failed. Instead, he posited that he would succeed every now and again with an invention that would change the world. The rest of the time, he tried thousands of other things with only one fault—they would never work.
This ‘glass half full,’ approach was key to Edison’s engineering success: culminating in the first commercially successful incandescent lightbulb. He then went on to invent the Universal Stock Printer to synchronize stock ticker transactions, quadruplex telegraph, and phonograph, securing over 1,000 U.S. patents for his various inventions.
Edison’s famous quote, "Genius is one percent inspiration and ninety-nine percent perspiration," reflects his belief in hard work and determination, reminding us that success often comes from perseverance, not just raw talent. In addition to honing your technical knowledge, cultivating a strong work ethic, collaborating with others, and continuously refining your skills will ensure you are on track to achieve your career goals and aspirations.
