A mechanical engineer is a specialist in all fields related to machines, kinematics, thermodynamics and tools. One of the oldest disciplines of engineering, mechanical engineering is one of the largest producers of engineers around the world today, closely followed by civil and aeronautical engineers. Working as a mechanical engineer is known to be an enriching and rewarding experience and the job description involves working to plan, build and examine motor-powered vehicles, manufacturing plants, airplanes, industrial equipment, cybernetics and much more. These engineers are in a highly lucrative position and considering that mechanical engineering is an extraordinarily comprehensive field, the engineer can specialize in a number of areas including, applied mechanics, bioengineering, manufacturing engineering and nuclear engineering to name a few. The oldest documented mechanical engineers can be traced back to Ancient Greece and can be seen in the works of Archimedes. Zhang Heng, the inventor of the seismometer and the water clock, lived between the periods of 78-139 AD, who left behind a great legacy related to ‘mechanics’ around the world. Here is a compilation of a list of famous mechanical engineers, learn more fascinating facts and details about them with their biographies that include trivia, interesting facts, timeline and life history.
