Foreign the mathematician, Robert Remak (mathematician)
Doctor Remak obtained his medical degree from Friedrich Wilhelm University in Berlin in 1838 specializing in neurology. He is best known for reducing Karl Ernst von Baer"s four germ layers to three: the ectoderm, mesoderm, and endoderm. He also discovered unmyelinated nerve fibres and the nerve cells in the heart sometimes called Remak"s ganglia.
He studied under Johannes Muller at the University of Berlin.
Remak discovered that the origin of cells was by the division of pre-existing cells. Rudolf Virchow, one of the founders of modern cell theory, plagiarized the notion that all cells come from pre-existing cells from Remak.
