Measurer of the Breathing Cell
A Nobel experimentalist who measured breathing cells with manometers and poisons, caught tumours gorging on sugar, then insisted, wrongly, that damaged respiration causes cancer.

Explore Otto Warburg’s life, respiratory-enzyme research, original papers and recorded Lindau lectures.
Born in Freiburg in 1883, Warburg trained in both chemistry and medicine. His research brought physical measurement to living systems: gases consumed, products released, reactions made visible.
In Berlin-Dahlem, he built a career around the chemistry of respiration, photosynthesis and tumour tissue.
Warburg used manometers to measure oxygen consumption and inhibitors such as cyanide and carbon monoxide to probe an iron-containing respiratory catalyst. Light reversed carbon-monoxide inhibition at particular wavelengths, linking the reaction to a haem group and helping earn the 1931 Nobel Prize.
The 1931 Nobel lecture is both result and method: gases, spectra and perturbations make an invisible enzyme experimentally legible. Later respiratory-chain research changed the molecular picture, but kept that insistence on measurable mechanism.
The Oxygen-Transferring Ferment of RespirationWarburg explains how inhibition, light and gas measurements identified a respiratory catalyst.Read the lecture · PDFWith Karlfried Wind and Erwin Negelein, Warburg measured tumour slices converting unusually large amounts of glucose to lactate even in oxygen. This counterintuitive aerobic glycolysis became known as the Warburg effect.
He went further in 1956, arguing that damaged respiration was the primary cause of cancer. Later human-tumour isotope studies show active glucose oxidation alongside increased glycolysis and substantial variation among tumours. The metabolic phenotype remains important; the universal causal theory did not prevail.
The Metabolism of Tumors in the BodyThe primary measurements behind aerobic glycolysis, before Warburg turned the finding into a general cancer theory.Read the paperAt Lindau in 1966, Warburg restated his cancer theory before an audience of scientists. The surviving recording lets us hear the argument in his own voice. He died in 1970.
The recording preserves a formidable experimentalist pressing a theory farther than later evidence would carry it. His legacy is therefore double: a durable metabolic observation and a caution about turning a recurrent phenotype into one universal cause.
