Carl Rabl (2 May 1853 in Wels, Austria– 24 December 1917 in Leipzig, Germany[1]) was an Austrian anatomist. His most notable achievement was on the structural consistency of chromosomes during the cell cycle. In 1885 he published that chromosomes do not lose their identity, even when they were not distinctly visible under the microscope.
Rabl studied the formation of the germ layers in embryos. He stained chromosomes and studied the interphase arrangement. His studies on salamander embryos suggested that the chromosomes occupy distinct territories in the interphase nucleus.[2]
