Robert Platt, Baron Platt

Robert Platt (1900-1978), later Lord Platt of Grindleford, was a British physician. His research was on kidney diseases, but he is remembered for the 1940-1950s Platt vs. Pickering debate with George Pickering over the nature of hypertension. Platt's position was that hypertension was a simple disease caused by perhaps just one genetic defect, and he presented evidence of its autosomal dominant inheritance and a bimodal distribution of blood pressures, indicating that hypertensives were a distinct subpopulation in humans. In contrast, Pickering's viewpoint was that blood pressures varied continuously and unimodally, with hypertensives representing the upper end of the bell curve. Though Platt's view was favoured during his lifetime, Pickering's view ultimately dominated and is the basis of current understanding and treatment policies.

During his lifetime, Platt held the salaried position of head of the Central Manchester Health Authority, and he later became the president of the Royal College of Physicians.
