Aaron Klug made many breakthroughs that advanced the knowledge of the basic structures of molecular biology, but he is best known for his creation of the new technique of crystallographic electron microscopy which made possible not only his own scientific discoveries but those of many other scientists as well. For his development of this technique as well as for his contributions to scientific knowledge, he was awarded the Nobel Prize in chemistry in 1982. He was also knighted as Sir Aaron Klug by Queen Elizabeth II in 1988.

Klug and his colleagues were able to reveal the structures and modes of operation of many basic biological materials such as viruses, animal cell walls, subcellular particles, chromatin from the genetic material of the cell nucleus, and various proteins.
