On July 3-4, 2018, an international workshop was organised at the University of Cambridge, by Dr.Nikoforakis, to mark the 80th anniversary of a young scientist, Philip Roe. Phil's scientific achievements are numerous, and it is quite difficult to adequately address his accomplishments in a short preface.Phil began his journey at Cambridge, first for his Bachelor's degree and then obtaining his Master's degree in 1962.He left for the Royal Aircraft Establishment (RAE) between 1962 to 1984 to work as an engineer.It was a period of adventure, and the design of mature CFD codes for solving the Euler equations was far from being achieved.Though the Lax-Wendroff theorem was known (published in 1960), as for many novelties, it had taken some time before it became a gold standard.At the RAE, Phil was assigned by his manager to work in a direction that eventually led to Roe's Riemann solver and flux.This method is now standard in every specialised textbook,but the jump from generalizing the Murman scheme for Euler equations to what is now commonly known as the Roe flux is far from obvious.Phil Roe relates this adventure, and others, in his "scientific autobiography", one of the papers of this focused issue.
