TMG (TransMoGrifier) is a compiler-compiler[1] created by Robert M. McClure and presented in 1968, and implemented by Douglas McIlroy.[2][3][4] TMG ran on systems like OS360 and early Unix.[5] It was used to build EPL, an early version of PL/I.[5] Ken Thompson used TMG in 1970 on PDP-7 as a tool to offer Fortran, but ended up creating the B programming language which was much influenced by BCPL.[2]
