J. B. Straubel

What strikes me about J. B. Straubel is how rarely his name surfaces in the Tesla story, despite fifteen years as chief technical officer building the batteries and powertrains that actually made the cars work. I have a soft spot for engineers who let the product speak instead of the press release. The Wisconsin-born, Stanford-trained inventor could have coasted on his reputation, yet he moved on to tackle battery recycling, arguably an even harder and less glamorous problem. That instinct to keep solving the unglamorous part is, to me, the mark of a genuine builder rather than a celebrity.
