Editing Hendrik Lorentz (section)

===Change of priorities===
In 1910, Lorentz decided to reorganize his life. His teaching and management duties at Leiden University were taking up too much of his time, leaving him little time for research. In 1912, he resigned from his chair of theoretical physics to become curator of the "Physics Cabinet" at [[Teylers Museum]] in [[Haarlem]]. He remained connected to Leiden University as an external professor, and his "Monday morning lectures" on new developments in theoretical physics soon became legendary.<ref name="NtvN2011"/>

Lorentz initially asked Einstein to succeed him as professor of theoretical physics at Leiden. However, Einstein could not accept because he had just accepted a position at [[ETH Zurich]]. Einstein had no regrets in this matter, since the prospect of having to fill Lorentz's shoes made him shiver. Instead Lorentz appointed [[Paul Ehrenfest]] as his successor in the chair of theoretical  physics at the Leiden University, who would found the Institute for Theoretical Physics which would become known as the [[Lorentz Institute]].<ref name="NtvN2011"/>
