Friedrich Hermann Leuchs (8 August 1879 – 2 May 1945) was a German chemist.
He transferred to the University of Berlin and received his PhD there in 1902 under Emil Fischer.
The ministry of education assured him that he would succeed Wilhelm Schlenk as head of the chemistry institute of the University of Berlin, but this never happened.
The Nazi regime, World War II and the destruction of Berlin increased his psychological problems, and shortly before the war ended he committed suicide in his flat in Berlin.
He was buried in a mass grave with numerous soldiers and citizens.
