Kathryn Betty Strutynski (born Latimer) (February 5, 1931 – April 9, 2010) was a mathematician and computer scientist educated at Brigham Young University and the Naval Postgraduate School. Her career included roles at Pan Am Airways, Bechtel Corporation, and most prominently at Digital Research, where she played a key role in the advancement of CP/M, recognized as the first widely adopted operating system for microcomputers.

Early life and education

Kathryn Latimer was born on February 5, 1931, in Nephi, Utah, to parents Andrew Hans Latimer and Henrietta Norton. She completed her bachelor's degree in mathematics at Brigham Young University in 1953 and subsequently spent two years teaching high school mathematics.

Career

In the early 1950s, Latimer relocated to San Francisco to join Pan Am Airways, overseeing all charter bid operations for the Western Division. When Pan Am centralized its offices in New York City, she was uniquely offered relocation assistance as the sole woman but chose not to move.

Her professional journey continued with positions at McGraw-Hill and later at Bechtel Corporation. At Bechtel, she participated in all available IBM training courses while spearheading a team of ten engineers to develop the company’s inaugural database retrieval system, which remained in use for a decade. In 1958, she married Alfred Waldemar Strutynski.

The couple settled in Carmel Village, California. In 1967, Kathryn enrolled at the Naval Postgraduate School (NPS), where she earned a master's degree specializing in computer programming. During her tenure at NPS, she administered the VM operating system and established a professional relationship with Gary Kildall, another expert in operating systems. Together, they engaged in informal enhancements of IBM VM-360 and VM-370 systems.

Digital Research

After leaving NPS, Kathryn Strutynski became the fourth employee hired by Digital Research, Inc. around 1978–1979. She was responsible for adapting CP/M-80 to function on the Apple II and contributed significantly to versions including CP/M 2.0, CP/M 2.2, CP/M Plus, as well as DESPOOL—a background print spooler that implemented basic multitasking capabilities. Additionally, she managed projects related to CP/M-86, Concurrent CP/M-86, and Concurrent PC DOS.

Around 1985, Strutynski returned to NPS to work at the W. R. Church Computer Center. There, she developed the PC laboratory and instructed courses on MS-DOS and WordPerfect, serving as Manager of Microcomputing Support and Learning Resource Centers.

From roughly 1997 until 2005, she operated her own firm, Strutynski Associates, based in Carmel.

Personal life

Kathryn Latimer met her future husband Alfred Waldemar Strutynski at a German dance hall; they married in 1958 and made their home in Carmel while Alfred served as an auditor for Monterey County. Throughout her career, Kathryn held significant roles at both the Naval Postgraduate School and Digital Research.

Death

Kathryn Strutynski passed away on April 9, 2010, aged 79, at her daughter’s residence in Calgary. Her husband died just two days later.

In popular culture

Her contributions were highlighted by Harold Evans in his book They Made America (2004). For the paperback edition released in 2006, Strutynski worked closely with Evans to revise and expand the section detailing CP/M’s inception.
