Werner Heisenberg
This year he published his theory of quantum physics at the age of 23. This theory helped in the discovery of allotropic forms of hydrogen. The theory is also known as the "uncertainty principle". To very briefly explain the theory, it is between the position and the momentum (Mass x Velocity) of a subatomic particle, such as an electron. References:
