Marlene Hazle facts for kids

Marlene Hazle (born May 8, 1934 – died June 7, 2011) was a smart American woman who made big contributions to computer science. She worked at important places like the RAND Corporation and Mitre Corporation. There, she helped create advanced computer systems such as SAGE and AESOP. Marlene also taught military staff how to use the SAGE computer system. She kept working on computer science and aerospace projects throughout the 1900s.

About Marlene Hazle

Marlene Hazle was born in Toledo, Ohio, in 1934. Her mom was a teacher, and her dad was an engineer. Marlene finished high school in 1952. Then, she went to Cornell University.

At Cornell, Marlene joined the Delta Gamma Sorority and Phi Beta Kappa. She also became the leader of Cornell's Mortar Board group. She took a class where her professor offered to show students how to use a computer for homework. Marlene was excited and started learning all about computers. In 1956, she graduated from Cornell with a degree in government.

Her Work in Computer Science

After college, Marlene started working at the RAND Corporation in Boston. At that time, RAND was getting people ready to work at special places called SAGE centers. SAGE was a US Military program during the Cold War. Its job was to use computers to watch US airspace for any planes from the Soviet Union.

The main computer for SAGE, called the AN/FSQ-7, was the biggest computer ever built back then! Marlene learned how to use these SAGE computers. She even became a teacher, showing others how to use the SAGE system.

After her work on SAGE, Marlene moved to MITRE. There, she designed and programmed a system called AESOP. The AESOP was one of the first "on-line" computer systems. These early on-line systems had many features we use today, like windows, computer mice, and links to other information. Marlene was one of the first people known to use an on-line computer.

Before the 1970s, computer programmers often kept their work secret. But Marlene believed in sharing and working together. She was one of the first people to push for programmers to collaborate. This idea of working together eventually led to what we now call open-source development. This is where people share computer code so others can use and improve it.

Marlene was also the secretary for a group called the Reuse Library Interoperability Group. This group helped companies and government agencies share and reuse computer code. Marlene Hazle passed away in Lexington, Massachusetts, in 2011, at age 77.

Important Contributions

Marlene Hazle made many important contributions to computer science:

• She helped the US Air Force with how they designed computer software.
• She shared her knowledge at the IEEE National Aerospace and Electronics Conference in the 1980s.
• She wrote about checking computer code and operating systems in a manual called Automated Requirements Development User Manual.
• She helped with the MIMSY Project and supported the author of a book about the Ada programming language.
• She was thanked for her early support in creating guidelines for designing computer user interfaces.
• She was listed as a contributor to the United States Air Force Program Office Guide to Ada.
• She reviewed a document about choosing Ada programming language compilers.
• She received special thanks for helping Arizona State University with their work on Ada computer environments.
• She shared her knowledge of DQL (Diana Query Language) to help with Ada computer designs.
• She contributed to a paper about how the Ada programming language could work with another system called Posix.
