Aaron Klug was born in 1926 in Lithuania; he studied in South Africa for his B.Sc and M.Sc. degrees. He received his Ph.D. in chemistry from Cambridge University in England, and in 1954 began working at Birckback College in London. From 1962, he began directing the MRC Laboratory of Molecular Biology.

In 1982, Aaron Klug was awarded the Nobel Prize in Chemistry “for his development of crystallographic electron microscopy and his structural elucidation of biologically important nuclei acid-protein complexes”.

Klug developed a method for deciphering the spacial structure of macromolecules by means of photographs taken with an electronic microscope. He also provided a theoretical basis for the reliability of his method.

In his research, Klug attempted to understand the connection between the organizing rules of macromolecules and their capability to perform various biological functions. In that, he laid the foundation for a fruitful research assisting in the comprehension of the macromolecule in fields such as viruses, the deciphering of the spacial structure of RNA-transfer and the structure of chromosomes bearing genetic information.
