There's an old tale about an engineer who charged $10,000 to fix a machine:
$1 for turning the right screw and $9,999 for knowing which screw to turn.
Well, it’s not just a legend — the engineer was real. His name was Charles Proteus Steinmetz (1865–1923), a brilliant mind in the field of electrical engineering.
One day, at Henry Ford’s River Rouge plant, a massive generator broke down. None of Ford’s engineers could figure out the problem. So, Ford called in Steinmetz.
When he arrived, Steinmetz asked for only three things: a notebook, a pencil, and a bed. He spent two days and nights listening to the machine, jotting down calculations.
Finally, Steinmetz requested a ladder, a tape measure, and a piece of chalk. He climbed up the generator, took a few measurements, and marked a spot with an X.
Turning to Ford’s engineers, he said, "Remove this panel, unwind the coil exactly here, and remove 16 turns of wire."
They did — and the generator roared back to life.
A few days later, Henry Ford received a bill from Steinmetz: $10,000.
Ford, surprised by the amount, asked for an itemized invoice. Steinmetz replied:
Marking the spot with chalk: $1
Knowing where to mark: $9,999
Without a second thought, Ford paid the bill.
This story was documented by Jack B. Scott, the son of one of Ford’s employees, in Life magazine in 1965.
Steinmetz was only about 4 feet tall, with a hunched back and uneven gait — but behind his unusual appearance lived one of the greatest scientific minds of the era, a friend to Albert Einstein, Nikola Tesla, and Thomas Edison.
