No, not at all, it was a Chinese farmer!
Most of the newest cars have a Back-Up Sensor that warns the driver before the rear bumper actually comes in contact with something. Most people probably think that this valuable feature came out of the minds of great engineers, but it was recently disclosed that the concept was first developed by a Chinese farmer.

Iceberg

In 1894, an Antarctic iceberg fragment was sighted at a latitude 26.50 degrees south, comparable to Rio de Janeiro. Reported by the ship Dochra, this remains the nearest to the equator that an Antarctic iceberg has been seen. Sightings of large icebergs as far north as 42 degrees south were made from 15 vessels in 1893. The Falkland Islands Gazette warned that year of exceptional ice conditions with large icebergs in shipping lanes around Cape Horn and commented: "Ice in this latter position is absolutely unknown, and must be looked upon as a great danger."«
