Context: The Grace Murray Hopper Awards (named for computer pioneer RADM Grace Hopper) has been awarded by the Association for Computing Machinery (ACM) since 1971. The award goes to a computer professional who makes a single, significant technical or service contribution at or before age 35., A learned society (also known as a learned academy, scholarly society or academic association) is an organization that exists to promote an academic discipline or profession, or a group of related disciplines or professions. Membership may be open to all, may require possession of some qualification, or may be an honor conferred by election., Computing is any goal-oriented activity requiring, benefiting from, or creating a mathematical sequence of steps known as an algorithm  e.g. through computers. Computing includes designing, developing and building hardware and software systems; processing, structuring, and managing various kinds of information; doing scientific research on and with computers; making computer systems behave intelligently; and creating and using communications and entertainment media. The field of computing includes computer engineering, software engineering, computer science, information systems, and information technology., Roger D. Moore was the 1973 recipient ( with Larry Breed and Richard Lathwell ) of the Grace Murray Hopper Award from the Association for Computing Machinery . His award from the ACM was as follows : For their work in the design and implementation of APL \ 360 , setting new standards in simplicity , efficiency , reliability and response time for interactive systems . Moore was a founder of I.P. Sharp Associates and held a senior position in the company for many years . Before this he contributed to the SUBALGOL compiler at Stanford University and wrote the Algol 60 compiler for the Ferranti - Packard 6000 and the ICT 1900 . In addition to his work on APL , he was also instrumental in the development of IPSANET , a private packet switching data network ., Grace Brewster Murray Hopper (December 9, 1906  January 1, 1992) was an American computer scientist and United States Navy Rear Admiral. In 1944, she was one of the first programmers of the Harvard Mark I computer and invented the first compiler for a computer programming language. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first high-level programming languages. She also popularized use of the term "bug" (already established in other technical contexts) in reference to computer software or hardware design failures., The Association for Computing Machinery (ACM) is an international learned society for computing. It was founded in 1947 and is the world's largest scientific and educational computing society. It is a not-for-profit professional membership group. Its membership is more than 100,000 as of 2011. Its headquarters are in New York City., Subject: roger moore , Relation: occupation, Options: (A) academic (B) compiler (C) computer (D) computer scientist (E) engineering (F) entertainment (G) pioneer (H) rear admiral (I) research (J) science
