Leonard Landois

Leonard Landois (1 December 1837 – 17 November 1902) was a German physiologist born in Münster.

He was a younger brother to zoologist Hermann Landois (1835–1905) and son-in-law to botanist Theodor Marsson (1816–1892).

His earlier work involved research in the field of parasitology, conducting studies of bed bugs, dog fleas and the parasitic worm Botriocephalus latus.

He also conducted studies on the ossification processes that take place in cartilage, tendons and connective tissue.

With this instructor, Ludwig Julius Budge (1811-1888), he investigated the phenomena of cardiac arrest during electrical stimulation of the vagus nerve.
