Laning and Zierler system
From Wikipedia, the free encyclopedia
Not to be confused with GEORGE (autocode system).
The Laning and Zierler system (sometimes called "George" by its users) was the first operating algebraic compiler, that is, a system capable of accepting mathematical formulas in algebraic notation and producing equivalent machine code (the term compiler had not yet been invented and the system was referred to as "an interpretive program"). It was implemented in 1952[1] for the MIT WHIRLWIND by J. Halcombe Laning and Neal Zierler. It is preceded by non-algebraic compilers such as the UNIVAC A-0.
