... by 1905 I had fairly in mind the specifications of the kind of car I wanted to build. But I lacked the material to give strength without weight. I came across that material almost by accident.

In 1905 I was at a motor race at Palm Beach. ... foreign cars...

After the wreck I picked up a little valve strip stem. It was very light and very strong. I asked what it was made of. Nobody knew.

...it was a French steel and that there was vanadium in it. We tried every steel maker in America—not one could make vanadium steel.

I sent to England for a man who understood how to make the steel commercially. The next thing was to get a plant to turn it out. That was another problem. Vanadium requires 3,000 degrees Fahrenheit. The ordinary furnace could not go beyond 2,700 degrees. I found a small steel company in Canton, Ohio. I offered to guarantee them against loss if they would run a heat for us. They agreed. The first heat was a failure. Very little vanadium remained in the steel. I had them try again, and the second time the steel came through. Until then we had been forced to be satisfied with steel running between 60,000 and 70,000 pounds tensile strength. With vanadium, the strength went up to 170,000 pounds.

Having vanadium in hand I pulled apart our models and tested in detail to determine what kind of steel was best for every part—whether we wanted a hard steel, a tough steel, or an elastic steel. We, for the first time I think, in the history of any large construction, determined scientifically the exact quality of the steel. As a result we then selected twenty different types of steel for the various steel parts. About ten of these were vanadium.
