1946 through 1958

Title of the proposed milestone:

The Grace M. Hopper Milestone - Grace Hopper created the compiler (translated mathematical notation into machine code) 1950-1952. The COBOL (COmmon Business-Oriented Language) 1952-1957 and implemented standards in early programming languages such as FORTRAN and COBOL in 1970

Plaque citation summarizing the achievement and its significance:

IEEE MILESTONE IN COMPUTER ENGINEERING & COMPUTER SCIENCE The invention of the compiler for computers, COBOL Language and Standards, in 1952

Grace Murray Hopper was one of the first programmers of the Harvard Mark I computer. She was a pioneer of computer programming and invented and coined the term compiler. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Grace developed the implementation of standards for testing computer systems and components, most significantly for early programming languages such as FORTRAN and COBOL. She coined the expression computer “Bug”. She retired from the Navy as Rear Admiral. Grace worked on many teams and programs. She was often referred to as “Amazing Grace”.

Street address(es) and GPS coordinates of the intended milestone plaque site(s):

447 N. Broad Street, Philadelphia, Pennsylvania 19123, 39.9613671, -75.1609546

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. The Mathematisc, Civices, and Sciences Charter School of Philadelphia, Inc. is a very successful STEM school for grades 1 to 12 grade with over 1000 students. It is own and the property it sits on by Veronica Joyner, M. Ed.

Are the original buildings extant?


Details of the plaque mounting:

The plaque will be placed In concrete in the sidewalk. This will be a Walk of Fame for Women of Science similar to Philadelphia's Avenue of The Arts and The Hollywood Walk of Fame. It is for the hidden figures of Science.

How is the site protected/secured, and in what ways is it accessible to the public?

It is protected by an insurance policy. Since it is in the sidewalk it is very visible to the public and is available for twenty-four hours a day and whenever anyone walks down the street. It will be extremely hard to pry the plaque out of the sidewalk. visible to the public

Who is the present owner of the site(s)?

Veronica Joyner, M. Ed., owns the property. Its current use is The Mathematics, Civics, and Science Charter School of Philadelphia, Inc. This is a very successful STEM school for grades 1 to 12 with over 1000 students.

What is the historical significance of the work (its technological, scientific, or social importance)?

The historical significance of Grace M Hopper's invention of the compiler is the importance of how it affected the modern computer: A compiler is a computer program that translates computer code written in one programming language into another language. The name compiler is primarily used for programs that translate source code from a high-level programming language to a lower-level language to create an executable program. Wikipedia

What obstacles (technical, political, geographic) needed to be overcome?

Grace M. Hopper's biggest obstacle was convincing her superiors and co-workers that it would work technically. The politics of convincing an all-male audience took three years for acceptance.

What features set this work apart from similar achievements?

The features that set this work apart from similar achievements is that is was the missing link in the program. She created an executable program that translated source code.

Supporting texts and citations to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or chapters in scholarly books. 'Scholarly' is defined as peer-reviewed, with references, and published. You must supply the texts or excerpts themselves, not just the references. At least one of the references must be from a scholarly book or journal article. All supporting materials must be in English, or accompanied by an English translation.

Supporting materials (supported formats: GIF, JPEG, PNG, PDF, DOC): All supporting materials must be in English, or if not in English, accompanied by an English translation. You must supply the texts or excerpts themselves, not just the references.
