"Lootie" has to be one of the best disaster-made inventions:

Looter Guy is not an invention. Looter Guy is an innovative genius who knows how to make the best of a bad situation.

3. Spectroscope. Joseph von Fraunhofer

4. The coin.

5. The clock.

6. Gregorian calendar

7. Anno Domini. Dionysius Exiguus

8. Thermodynamics. Sadi Carnot.

9. Quantum mechanics. Max Planck
