'Belar next studied the mechanism of mitosis in the cells of higher plants and animals, particularly the formation and activity of the achromatic apparatus and its function… in the separation of the chromosomes. His work was based on live observation of dividing cells, primarily spermatocytes of a grasshopper (Chorihippus) and mitosis in the hair cells of the anthers of the spiderwort, Tradescantia. In the spindle he distinguishes chromosomal fibers that are attached at one end to the centromere of the chromosomes and at the other end to the spindle poles. These fibers shorten considerably during anaphase and thus pull the chromosomes toward the spindle poles. The other component is the middle region of the spindle, which connects the two poles and in araphase lengthens and pushes the spindle poles further apart, thus aiding the further separation of the chromosomes attached to the poles. The action of the middle region was suggested by experiments in which dividing cells were put into hypertonic solutions. In this treatment the cytoplasm shrinks due to loss of water, finally forming a thin layer around the spindle. The spindle, on the other hand. lengthens considerably, particularly in anaphase cells. and frequently gets bent on itself because it meets the resistance of the reduced cytoplasm. Belar's findings and conclusions formed the basis of later discussions of the nature of mitosis. The reality of the spindle fibers and the longitudinal structure of the central spindle was in doubt for twenty years because, though quite conspicuous in fixed preparations, they cannot be seen in living cells. Belar supported their existence by indirect observations and conclusions. Only in 1953 was Inoue able to demonstrate their existence in living cells by means of polarization microscopy and to show the fibrous nature of the middle region. Since that time the picture has become more concrete by the employment of the electron microscope, which has shown both chromosomal fibers and central spindle fibers, and by biochemical studies of the behavior of tubulins, the main protein component of the spindle. The fibers of the middle region, which extend from one pole to the other, lengthen during anaphase, as Belar envisioned; but it is now generally agreed that sliding of fibers against each other is probably the source of spindle elongation. . . . Belar had a very sharp and critical mind, and was famous and feared for his severe criticisms. He had little patience with inexact technique and sloppy thinking, and had the courage to attack even the most influential biologists of his time for instance. Rudolf Flick, the head of the Anatomy Department in Berlin; the protozoologist Franz Doflein; the zoologist Alfred Kühn; and even his supervisor Hartmann, who complains about Belar's sharply critical remarks in the foreword he wrote for Belar's monograph on protozoan nuclei. But Belar used the same ruthless criticism against his own work and his earlier publications. . . . Belar's significance in the history of cytology consists in the fact that he mercilessly destroyed many assumptions that were based on poor observations and wrong interpretations, and replaced them with carefully considered and solidly based ideas. Most of these are still valid, though superior methods have made them more concrete' (Ernst Caspari, 'Karl Belar', Dictionary of Scientific Biography). 'He was invited as a guest lecturer at California Institute of Technology by T.H. Morgan and worked there between 1929 and 1931. Just before his return to Berlin he was killed in a car accident in the Mojave desert near Victorville where he had visited so as to paint a landscape.'.
