In Königstein im Taunus, which housed the sanatorium his student and son-in. he resided after his retirement from 1912 to 1915. There is also the grave of his only son died in the wars of the same name (John Gad 1888-1916 ).

In his career was Gad assistant of Emil Heinrich Du Bois -Reymond (1818-1896) at the Physiological Institute of the University of Berlin, 1879-1885 and worked under Adolf Fick at the University of Würzburg. There he was appointed on 22 October 1887 associate professor at the Faculty of Medicine of the Royal Friedrich- Wilhelms- University and for adoption of a full professorship at the German University in Prague end of October 1895 dismissed from this position.

With the neurologist Edward Flatau he led in 1893 in Berlin experimental work on dogs by. In the years 1893-1894 he was a visiting lecturer at the physiological institute of the Western Reserve University in Cleveland, Ohio. After his return to Germany, he became head of the physiological institute of the University in Berlin. In 1895 he followed Ewald Hering ( 1834-1918 ) as head of the Department of Physiology at the University of Prague, where he worked with Arnold Pick.

Gad is known for his work on experimental physiology. He conducted numerous studies on the electrophysiology, spinal cord functionality and the relationship between lactic acid in muscle contraction and other. Among his written works was a textbook on human physiology, which he brought out along with the pharmacist Jean -François Heymans: " Short Textbook of Human Physiology ", and a treatise on skin stimuli that he together with Alfred Goldscheider (1858-1935 ) published. The book was reissued in 2007.
