Injustice to metallurgists !!!!!!!!!

Here are a few of the major milestones in the discovery of dislocations:

Theory of Elasticity Timpe (1905)
Volterra (1907)
Theoretical shear limit Frenkel (1926)
"Verhakungen" Dehlinger (1929)
Postulate of (edge) dislocations Orowan (1934)
Polanyi (1934)
Taylor (1934)
Postulate of screw dislocationsBurgers (1939)
Multiplication mechanisms of dislocations Frank-Read (1950)
Direct observation of dislocations (TEM) Hirsch et al. (1956)
Dislocation free Si crystal growthDash (1960)

These discoveries solved the 3000 year old puzzles of metallurgy! But no Noble prizes were awarded and mankind hardly noticed that something big has happened.

What a grave injustice to metallurgists !!!!!!!
