TLDR: Alick Glennie was a British computer scientist known for developing Autocode, the first computer compiler. He worked with Alan Turing and made significant contributions to the field of computer science.
Alick Edwards Glennie, who lived from 1925 to 2003, was a computer scientist from Britain. He is most famous for creating Autocode, which is considered to be the first ever computer compiler. Autocode is a program that translates human-readable code into a language that computers can understand. This was a major breakthrough in computer programming because it made it easier for people to write programs for computers.
Glennie had the opportunity to work with Alan Turing, another famous computer scientist, on various projects. One of these projects was the Manchester Mark 1, a computer developed at the University of Manchester. Working alongside Turing, Glennie contributed to the development of this early computer.
Later in his career, Glennie worked at the Atomic Weapons Research Establishment (AWRE). During the early 1960s, he played a key role in developing FORTRAN compilers for several large computers, including the IBM 709, IBM 7090, IBM 7030 ("Stretch"), and ICT Atlas. He even pioneered a method of developing the compiler for the Atlas on the IBM 7030 before the Atlas was even delivered, using an interpretive technique.
In summary, Alick Glennie was a British computer scientist who made significant contributions to the field of computer science. He developed Autocode, the first computer compiler, and worked with Alan Turing on various projects. His work at the Atomic Weapons Research Establishment further advanced the development of computer programming.
