Biography
John Leslie, born in 1766, was a distinguished natural philosopher whose work at the University of Edinburgh combined mathematical rigor with a love of the natural world, producing investigations of heat, light, and sound that included the celebrated Leslie cube and new instrument designs to measure temperature.
He mentored generations of students, maintained friendships with scientists across Europe, and enriched the study of natural history through both experimental inquiry and generous counsel, passing away in 1832 and being laid to rest in the parish of Upper Largo.
