The left end consisted of electromechanical computing components. The right end included data and program readers, and automatic typewriters. The Harvard Mark I, or IBM Automatic Sequence Controlled Calculator (ASCC), was one of the earliest general-purpose electromechanical computers used in the war effort during the last part of World War II.
Grace Brewster Hopper (née Murray; December 9, 1906 – January 1, 1992) was an American computer scientist, mathematician, and United States Navy rear admiral. [1] She was a pioneer of computer programming.
Richard Milton Bloch (June 18, 1921 – May 22, 2000) was a pioneering American computer programmer. Bloch, Grace Hopper, and Robert Campbell were the first programmers of the Harvard Mark I, an electromechanical computer which, when it began operation in 1944, was the first American programmable computer.

The first implemented compiler was written by Grace Hopper, who also coined the term "compiler", [6] [7] referring to her A-0 system which functioned as a loader or linker, not the modern notion of a compiler. The first Autocode and compiler in the modern sense were developed by Alick Glennie in 1952 at the University of Manchester for the Mark ...
Grace Hopper was the first person to create a compiler for a programming language and one of the first programmers of the Harvard Mark I computer, an electro-mechanical computer based on Analytical Engine. Hopper's work with computers started in 1943, when she started working at the Bureau of Ordnance's Computation Project at Harvard where she ...
Designed and built the Mark II Colossus computers; superseded the Mark I version (which was the world's first digital, electronic computing device) 1989 Corbató, Fernando J. Pioneering work organizing the concepts and leading the development of the general-purpose, large-scale, time-sharing and resource-sharing computer systems CTSS and Multics
This computer was originally called the ASCC (Automatic Sequence Controlled Calculator) and later renamed Harvard Mark I. With engineering, construction, and funding from IBM, the machine was completed and installed at Harvard in February 1944. [5] Richard Milton Bloch, Robert Campbell and Grace Hopper joined the project later as programmers. [6]
Detailing, in poetic style, the first computer algorithm; a description of exactly how The Analytical Machine should have worked based on its design. Grace Murray Hopper: a pioneer of computing. She worked alongside Howard H. Aiken on IBM's Mark I. Hopper and also came up with the term "debugging."
