Abstract
In 1971, Walther Stoeckenius discovered that Halobacterium halobium contains a purple pigment that is chemically similar to rhodopsin and works as a light-driven proton pump. This discovery set Stoeckenius on a research path centered on bacteriorhodopsin, which included the creation of a bovine-soybean-halobacteria chimera that was able to produce ATP when exposed to light and the discovery of a class of proteins that are phosphorylated in a light-dependent manner.

In 1952, he began postdoctoral work at the Institute for Tropical Medicine in Hamburg, using electron microscopy to study the development of pox viruses
At Hamburg, Stoeckenius continued to use electron microscopy to explore the fine structure of cells and the lipid membrane
