He discovered the nonmedullated nerve fibres in 1838, and in 1844 the nerve cells of the heart, called Remak’s ganglia.Also, what type of scientist was Robert Remak? Robert Remak (1815–1865) Robert Remak was a neurologist, a physiologist, and an embryologist. He was born on July 23, 1815 in Poznań; this town and a large western part of Poland was occupied by Prussia during his lifetime. In his papers, written in Polish, he refers to Poles as his compatriots [3]. Beside above, when did Robert Hooke contribute to the cell theory? 1665 Who created the modern cell theory?Many scientists have made discoveries relating to cell theory, but three scientists are usually given credit for its development: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Together, these scientists put forth the three basic tenets of modern cell theory: All living things are made up of cells.
