  "account": "In September 1976, physicist Masao Doi published two groundbreaking papers in the Journal of Physics A that introduced classical stochastic many-body problems using mathematical language similar to quantum-field theory.\n\nDespite the timing, the theory remained unknown for many years, being reinvented in 1980 by Peter Grassberger and Martin Scheunert. The theory was further developed when Luca Peliti, at the University of Rome, put the theory into a path integral formalism, making it amenable to renormalisation.\n\nThe pair met for the first time at a conference in Cambridge in 2018, which celebrated the work and 50 years of the Doi-Peliti theory. This marked the first time Doi, the chief scientist at the Wenzhou Institute of the University of Chinese Academy of Sciences, learned about his theory's name and the subsequent developments.",
