Lommel differential equation was developed by the German physicist who was the doctoral advisor to another German Physicist who identified the Stark effect.
Eugen Cornelius Joseph von Lommel (19 March 1837, Edenkoben  19 June 1899, Munich) was a German physicist. 
 He is notable for the Lommel polynomial, the Lommel function, the LommelWeber function, and the Lommel differential equation. 
 He is also notable as the doctoral advisor of the Nobel Prize winner Johannes Stark. 
Johannes Stark (] , 15 April 1874  21 June 1957) was a German physicist and Physics Nobel Prize laureate. 
 He is known for identifying the Stark effect, and was later closely involved with the "Deutsche Physik" movement under the Nazi regime.
