George Westinghouse died in New York City, at age 67. As a Civil War veteran, he was buried in Section 2 of Arlington National Cemetery, along with his wife Marguerite, who survived him by three months. Later to be called "The Perfect Partnership" there is little doubt about the impact Westinghouse and Tesla had upon the world.
Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop. The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum wireless light, my turbine engine and many other devices have all been developed in exactly this way.
