Sally Shlaer
Sally Shlaer ( born December 3, 1938 in Cleveland, Ohio, † 12 November 1998 in Berkeley, California ) was an American mathematician and software engineer. She is best known as the co- developer of the Shlaer - Mellor method for software development in the 1980s.
Life
Sally Shlaer was the daughter of Arthur and Naomi Slaughter. When she was ten years old, the family moved to Phoenix. In 1960, she received at Stanford University with a Bachelor of Science in Mathematics. Here she wrote her first software in Fortran and Assembler code to reduce data volumes in the experimental physics. After her marriage she moved to Austin (Texas ) and started a family. Then Shlaer moved to Canberra ( Australia) and attended the Graduate School at the Australian National University.
1965 Shlaer returned back to the United States and moved to Los Alamos (New Mexico). There she began as a software engineer at Los Alamos National Laboratory. In the early 1970s she had sole responsibility for the supervision and control of software for the Los Alamos Biomedical Treatment Facility. In 1977, she left Los Alamos and was project manager of software development at the Lawrence Berkeley National Laboratory, where two years later led the development of a new integrated control system for the Bay Area Rapid Transit system. The project objective was to analyze the outdated and poorly maintainable software ( about 70,000 lines of code in Fortran and Assembler) and by a new replace ( at the end of 2000 lines of code). During this project Shlaer met for the first time Stephen J. Mellor, who was then head of the software infrastructure group. Together they developed while the Shlaer - Mellor method for software development and in 1985 they founded the software development company Project Technology Inc. Their method they spread in lectures and seminars.
Shlaer was a Fellow of the Association for Computing Machinery (ACM ).
Shlaers last years were clouded by a chronic disease. Although this had affected their productivity, she was still able to carry out important research on recursive style.
Services
Sally Shlaer was one of the few women in the male-dominated world of design methodology for software and a leading scientist in the so-called object-oriented approach to software development. From the teachings of the re-engineering of software for public transport in San Francisco, she developed with Stephen Mellor the Shlaer - Mellor method ( also Object Oriented System Analysis ( OOSA ) or Object Oriented Analysis (OOA ) ) of software development. In the 2000s, it developed into Executable UML.
Shlaer began their software engineering career at the Los Alamos National Laboratory as a programmer. They designed and implemented in assembler code for a SEL 810A computer a real-time, multitasking -capable operating system for an electron accelerator. Her specialty was then first real-time and process control software for the purpose of physical research.
