C. R. Rao (1920–2023)

[...]his methods were used to uncover signs of the Higgs boson in data from CERN - Europe's particle-physics laboratory near Geneva, Switzerland. [...]in his master's thesis (1943), through analysing data from populations living in the Indian state of Uttar Pradesh, he developed the 'perimeter' test for comparing two or more experimental groups. In 1943, in response to a student's question, Rao derived a lower bound (now known as the Cramér-Rao inequality) for estimating unknown parameters of a statistical population, such as the average reduction in people's blood pressure ca used by a new drug.
