Johan Albert Levan (born March 8, 1905 in Gothenburg , † March 28, 1998 in Lund ) was a Swedish botanist and geneticist .
Levan described the use of colchicine as a mitosis inhibitor in 1938 . He ran the laboratory where Joe Hin Tjio discovered the correct number of 46 chromosomes in the human genome in 1956 and was co-author of Tjio's paper.
From 1961 to 1973 Levan was Professor of Cell Biology at Lund University , where he headed the cancer chromosome laboratory at the Institute of Genetics.
