Early life and education Edit

Kathryn Betty Latimer was born on 5 February 1931[2] in Nephi, Utah, USA. Her father was Andrew Hans Latimer and her mother Henrietta Norton.[1][3]

Latimer obtained an undergraduate degree in mathematics from Brigham Young University in 1953,[4] and taught high school mathematics in Utah for two years.

Career Edit

In the early 1950s, she moved to San Francisco, where she worked at Pan Am Airways doing research. Kathy eventually became responsible for all the charter bids at the Western Division of Pan Am. When Pan Am consolidated its offices in New York Latimer was the only woman to be offered moving expenses to relocate to New York, but she declined the offer.

After Pan Am, Kathryn Latimer worked at McGraw-Hill[5] and the estimating department of Bechtel Corporation.[5] When the company decided to purchase a mainframe computer, Latimer was sent to take every class given at IBM. In 1952 and 1953, she built the company's first database retrieval system, with 10 engineers working under her charge, renting computer time since they did not have a mainframe computer at that time. The database was used for a period of ten years.[5] In 1958, she married Alfred Waldemar Strutynski.

Kathryn Strutynski's husband moved to Monterey, California to work for the County of Monterey as an auditor. The couple lived in Carmel Village, where she worked at the Naval Postgraduate School (NPS) since 1967[4][6] and completed a master's degree program in computer programming at the same time. Strutynski was given system responsibility for the VM operating system at the NPS.[5] At the same time, Gary Kildall also taught at the NPS[4] and was interested in operating systems. They became friends,[7] studied and made unofficial changes to the IBM VM-360 and 370.[4][8][9]

Digital Research Edit

Main article: Digital Research

Kathryn Strutynski left NPS[10] and, in 1978[8]/1979,[11][6] became the fourth employee of Digital Research, Inc.[11][12] She adapted CP/M-80 for the Apple II[5][13][citation needed] and worked on CP/M 2.0,[7] CP/M 2.2,[14][15][12] CP/M Plus,[16][14][15] and DESPOOL, a background spooler for printing (utilizing simple multi-tasking)[17] as well as on the system guides. She also was the project manager for CP/M-86,[14][15][12] Concurrent CP/M-86[12] and Concurrent PC DOS.[18]

Around 1985, Strutynski returned to work for NPS at the W. R. Church Computer Center,[19] where she raised the PC lab[19] and taught MS-DOS and WordPerfect courses[20] as Manager of Microcomputing Support[21] and Learning Resource Centers.[22]

In her later years she ran Strutynski Associates in Carmel.[23]

Personal life Edit

Kathryn Latimer met Alfred Waldemar Strutynski in a German dance hall. They married in 1958 and moved to Carmel since her husband had started working for Monterey County as an auditor. She worked for the Naval Postgraduate School in Monterey and later at Digital Research.[24]

Death Edit

Kathryn Strutynski died on 9 April 2010 at her daughter's home in Calgary while she was 79. Her husband died two days later.[25][24]

In popular culture Edit

Harold Evans wrote about her in his book They Made America (2004).[26] For the reworked paperback issue (2006), Strutynski spent many hours working with Evans updating the chapter of his book related to the birth of CP/M.[5][12][27]

That was a very strange question. I soon learned that he had been wandering around all day probably thinking about some new algorithm and he did not know where he had left his punched cards. At this time the cards were his only important possession. Gary didn't talk to me about working for him. He just came into my office, picked up my briefcase. This was a common occurrence. He walked me to my car and said: "I can afford you." We never discussed when or how much. (1 page) (NB.

[…] 79 - Kathryn Betty Strutynski, a long-time resident of Carmel, passed away on April 9, 2010, at the home of her daughter, Karen. Born in Nephi, Utah, she attended Brigham Young University where she obtained an undergraduate degree in mathematics. In her early 20's, Kathryn moved to San Francisco, where she went to work for Pan Am Airways. Here, she was responsible for all charter bids at the Western Division of Pan Am. When Pan Am consolidated its offices in New York, Kathryn was the only female employee offered moving expenses to relocate […] However, Kathryn decided to stay in her beloved San Francisco. Kathryn then went to work at the estimating department of Bechtel Corporation in San Francisco. Bechtel sent her to every class given at IBM when the company decided to purchase a mainframe. With her new knowledge, Kathryn ended up building the company's first database retrieval system. Bechtel kept her database system for ten years. In 1958, Kathryn married an Austrian, Alfred Strutynski, and they moved to Carmel. While living on the Peninsula, Kathryn worked for the Naval Postgraduate School in Monterey and obtained her master's degree in computer programming through the school. At NPS, Kathryn was given system responsibility for the VM operating system. Because of this, a Navy professor by the name of Gary Kildall, who was very interested in all operating systems, developed a deepfriendship with Kathryn. The two of them made unauthorized changes to the IBM VM-360 and 370 system code. IBM never let them see the code again. A few years later, Kathryn left NPS, when in her words, "Gary walked into my office, picked up my briefcase, and said, 'I can afford you.'" She then became the fourth employee of Gary's company, Digital Research Inc. At DRI, Kathryn watched excitedly as Gary completed work on the first computer operating system known as CP/M or Control Program for Microcomputers. The foundations of this operating system were later to become the basis for both QDOS and MS/DOS. The computer company, IBM, was very excited by the possibilities of this new operating system and tried to bargain with DRI to sell it this new product. When Gary became hesitant to sell CP/M to IBM, it was Kathryn who was called late one evening at home by Bill Gates of Microsoft Corp. and asked to intercede with Gary. However, the sale was not to be, and the rest, as they say, is history. Kathryn stayed on at DRI and continued to write code for new versions of CP/M. She worked on CP/M 2.0 and [CP/M Plus]. She made many contributions to CP/M 2.2 (the largest money spinner for DRI) including a background spooler for printing (simple multi-tasking) and system guides. In fact, in one book, Kathryn is called "the mother of CP/M 2.2," for the hundreds and hundreds of hours she put in with Dave Brown, John Pierce, Bob Silberst[ei]n, and others, perfecting Kildall's original design. Kathryn was also the project manager for CP/M-86 and Concurrent CP/M-86. While at DRI, Kathryn gave seminars on hardware implementation in Brussels, Wokingham, England, and Munich, Germany. One of Kathryn's biggest thrills in later life was meeting the author Sir Harold Evans while he was re-writing parts of his book, "They Made America," for the release of its paperback version. Kathryn spent many long hours working with Sir Harold Evans updating the chapter of his book relating to the birth of CP/M and her beloved Gary Kildall's contributions to the field of computing. […]

edition but discovered that it was full of mistakes so he came to a conference at Asilomar with the thought particularly in mind that he would look up Kathy and get the straight scoop Another of Kathy s projects in those days at NPS was Interp It was a system running on the mainframe under VM which would allow you to simulate systems written for PC s You could work out the bugs using Interp on the mainframe and then know it would work on the PC Getting Interp running well was a challenge Kathy was grateful to have capable NPS grad students working with her For Digital Research Kathy made CP M

s degree in computer programming through the school At NPS Kathryn was given system responsibility for the VM operating system Because of this a Navy professor by the name of Gary Kildall who was very interested in all operating systems developed a deepfriendship with Kathryn The two of them made unauthorized changes to the IBM VM 360 and 370 system code IBM never let them see the code again A few years later Kathryn left NPS when in her words Gary walked into my office picked up my briefcase and said I can afford you She then became the fourth employee of Gary s company Digital Research Inc At DRI Kathryn watched excitedly as Gary completed work on the first computer operating system known as CP M or Control Program for Microcomputers The foundations of this operating system were later to become the basis for both QDOS and MS DOS The computer company IBM was very excited by the possibilities of this new operating system and tried to bargain with DRI to sell it this new product When Gary became hesitant to sell CP M to IBM it was Kathryn who was called late one evening at home by Bill Gates of Microsoft Corp and asked to intercede with Gary However the sale was not to be and the rest as they say is history Kathryn stayed on at DRI and continued to write code for new versions of CP M She worked on CP M 2 0 and CP M Plus She made many contributions to CP M 2 2 the largest money spinner for DRI including a background spooler for printing simple multi tasking and system guides In fact in one book Kathryn is called the mother of CP M 2 2 for the hundreds and hundreds of hours she put in with Dave Brown John Pierce Bob Silberst ei n and others perfecting Kildall s original design Kathryn was also the project manager for CP M 86 and Concurrent CP M 86 While at DRI Kathryn gave seminars on hardware implementation in Brussels Wokingham England and Munich Germany One of Kathryn s biggest thrills in later life was meeting the author Sir Harold Evans while he was re writing
