    2. Grace Hopper Biography Tam Nguyen - Section 101 1906:Born in New York City 1928:graduated from Vassar College with a BA in mathematics and physics and joined the Vassar faculty. 1934: received a PhD in Mathematics from Yale University 1943: joined the Navy 1944: started working with Aiken on the Harvard Mark I computer The picture is from http://leiron.be/exttopics/gracehopper.html The picture is from http://leiron.be/exttopics/gracehopper.html

    3. Grace Hopper Biography Cont. Tam Nguyen - Section 101 1951 invented the compiler, the cornerstone of all high end programming languages. 1951-1957 Hopper and her staff created the first commercial high end mathematical and business computer languages, MATH-MATIC and FLOW-MATIC. 1953 named directorof automatic programming for the first commercial computer, UNIVAC. 1959 organized the conference that created the business language COBOL. 1967 returned to active service in the US Navy after seven month retirement.

    4. Programming the First Computers Tam Nguyen - Section 101 Third person to program the Mark I. Program Mark I, Mark II, and Mark III Computer at Harvard. Received the Naval Ordnance Development Award for the success on the Mark I, Mark II, Mark III. Began another pioneering effort of UNIVAC I, the first large-scale electronic digital computer.

    5. First computer bug Tam Nguyen - Section 101 Refers to a moth stuck between the relays on the Mark II. The operators removed the moth and affixed it to the log. (See the picture above.) The entry reads: "First actual case of bug being found. The word went out that they had "debugged" the machine and the term "debugging a computer program" was born. Hopper was the first person to 'debug' a computer.

    6. Compilers

    7. COBOL and its validation Tam Nguyen - Section 101 Pursuing her belief that computer programs could be written in English. Invented B-O compiler, later known as FLOW-MATIC. Using B-O, she developed COBOL (COmmon Business-Oriented Language). Under her direction, the Navy developed a set of programs and procedures for validating COBOL compilers. This concept of validation has had widespread impact on other programming languages and organizations.
