Shinya Inoue was born in 1921, and is primarily a biophysicist (although he is currently a researcher at the Marina Biological Laboratory) and a member of the National Academy of Sciences. His research field is the visualization of dynamic processes within living cells using the light microscope. He has both a Ph. D. and an M.A. in biology from Princeton University. He also has something known as a “Rigakushi”, in zoology from the Tokyo University in 1944. Inoue is considered to be the father in the field of cytoskeleton dynamics. By using polarization microscopy in the 1940s and 1950s, he’s proven for the first time ever that the mitotic spindle is composed of aligned protein fibers (the fibers are now known as microtubules). He also went on to working even further with the spindle fibers, and discovered that artificial polymerization and deploymerization of spindle fibers can generate forces within the cell, and he proposed that chromosomes are normally moved by such forces during mitosis. In addition, during his work with the Marine Biological Laboratory (M.B.L.), he was honored by the government of Japan with the Order of the Sacred Treasure, Gold Rays with Neck Ribbon award. The mentioned award “recognizes Inoue’s contributions to science and the development of technologies, and the promotion of research cooperation between Japan and the United States”. Inoue’s greatest contribution was to pioneer the microscopic imaging of live cells by inventing new ways of using light to investigate the details of the cellular structure and dynamics. According to one article by an anonymous author, Dr. Shinya Inoue presented the 2003 International Prize for Biology on December 1 by the emperor of Japan and the Prime Minister Koizumi Junichiro. It was given to him for the promotion of science and to commemorate the 66 year reign of emperor Showa and his longtime interest in biological research. Dr. Inoue was actually chosen from 41 other scientists, whom were nominated from 14 different countries to receive this remarkable prize in the area of cell biology. Dr. Shiya…
