“In October 1911 Planck took part in the first Solvay conference initiated by his colleague Walther Nernst to discuss the consequences of his radiation law for physics. The conference itself had no result – Albert Einstein later described it as “a lament for the ruins of Jerusalem”– but sharpened the awareness of the physicists present for the problems posed and led to an increasing number of young physicists also dealing with quantum theory. This generation finally developed modern quantum mechanics in the 1920s. Planck himself was extremely sceptical about further developments and continued to try to reconcile his law of radiation with classical physics” (‘Max Planck and Quantum Theory’, SciHi Blog).
