Albert Levan is best known today for co-authoring the report in 1956 that humans had forty-six chromosomes (instead of forty-eight, as previously believed). This epochal discovery was made by Joe Hin Tjio in Levan's laboratory.
Originally specialising in plant cytology, Levan later turned to the similarities in the chromosome structure of cancer cells and errors introduced to plant cells via chemical or radioactive elements. These studies later led to examination of chromosomes in animal cells.
Levan was elected a member of the Royal Swedish Academy of Sciences in 1967.
