Professor Frank Matthews Leslie FRS FRSE (8 March 1935 – 15 June 2000) was a Scottish mathematical physicist specializing in continuum mechanics.
He is remembered for the Ericksen–Leslie Theory which he developed with Jerald Ericksen to describe the viscosity of mesophases associated with liquid crystals.
The parameters of this theory are viscosities called "Leslie coefficients", and the angle at which a (flow aligning) nematic orientates with respect to the direction of flow in a steady shear flow is called the "Leslie angle".
