German biochemist Karl Lohmann discovered adenosine triphosphate (ATP), the key source of energy in all living things, in 1929. He isolated ATP from muscle and liver extracts, and originally called his discovery "inosinic acid". He worked for several years under Otto Meyerhof, Nobel laureate for his elucidation of the glycogen-lactic acid cycle, but Lohmann never received Nobel honors himself a curious oversight, since his discovery was a major development in early biochemistry, and is virtually synonymous with biochemical energy.

Lohmann also discovered cocarboxylase, now known as thiamine pyrophosphate (TPP) or thiamine diphosphate (ThDP), a vitamin B1 derivative produced by thiamine pyrophosphatase. In 1935, in a phenomenon still known as the Lohmann reaction, he found that ATP and creatine phosphate (PCr) are held in equilibrium by creatine kinase. During his nation's Nazi era and the subsequent communist era that lasted until after his death, he joined neither the Nazi nor Communist parties. He retired in 1964, and died fourteen years later. He is the namesake of the Karl Lohmann Prize, awarded by the German Society for Biological Chemistry.
