Lorinda Cherry

Cherry died in February 2022, at the age of 77. Her death was announced on February 16, 2022. She was survived by her sister, Carynn Kelley-Katz.

One of the last projects Cherry did was an analysis of transcriptions of calls to AT&T Trouble Centers, searching these inconsistently formatted texts for evidence of systemic problems. The work resulted in changes in AT&T's internal policies. She was one of three co-inventors listed on AT&T's patent on a "Method and system for verifying the status of 911 emergency telephone services". In July 1994 Cherry was part of a group that worked to make AT&T's 1-800 numbers directory available on the nascent Internet. The team dealt with both technical and political issues to produce the online directory, which became one of the first "Cool links" identified by Yahoo!.

Cherry was involved in development of Bell Labs's Writer's Workbench (wwb) writing toolsuite, to the extent that she considered herself the project's "grandmother". The project was conceived of by Rutgers professor William Vesterman, who wanted a tool that could analyze writing style. Cherry updated parts for Vesterman's project, and wrote two new programs — style and diction — for it, which was expected to be the extent of her involvement. Development of what became Writer's Workbench was led by Bell psycholinguist Nina Macdonald of the Human Performance Engineering Department. Macdonald contacted Cherry to ask permission to use parts for Writer's Workbench. In addition to Alfred Aho's pattern search work, Writers Workbench would use at least three technologies that Cherry had already worked on: electronic typesetting, parts-of-speech analysis, and statistical analysis of speech. While Macdonald worked on the front end and integrating the program's utilities, Cherry continued to write code for the back end of the project. Cherry and Macdonald collaborated on an article for Bell Laboratories Record magazine in May/June 1983, an article in Byte magazine in October 1983, and a presentation delivered to a joint meeting of the psychology and computer science divisions of the New York Academy of Sciences in 1981. Both also presented the software to a television audience on two occasions; on NBC's Today show in May 1981, and on New York's WCBS Channel 2 News in August 1983. After letting Andrew Tanenbaum use the program on an early draft of a book he was writing, Cherry commented on the ability of tools like Writer's Workbench to improve the quality of written text not only by correcting errors, but by changing how writers write. She stated:

After the wwb was released in 1980, Bell Labs incorporated it into company-wide writing workshops.

Cherry made several contributions to the development of electronic typesetting, many related to troff. She cowrote the 1979 edition of "Typing Documents on the UNIX System: Using the –ms and –mcs Macros with Troff" with Mike Lesk for the Unix Tenth Edition Manual. Cherry and Lesk created tbl, a tool for formatting tables. She personally authored deroff, which strips all troff commands from the input. Cherry programmed a video display so that typeset documents could be previewed on a screen rather than having to create a photographic print. She also made contributions to TeX.

Cherry was promoted to a Member of the Technical Staff (MTS) in 1976, giving her more freedom to pursue her own projects. One of the first projects that she personally initiated after becoming a member of the technical staff also involved use of trigrams to compress the text contained in a telephone directory.

In 1971 Cherry joined the Computing Science Research Center, where her work focused on graphics, word processing, and language design. Some of her earliest work there consisted of configuring systems to run an early version of Unix written in assembly language. She was introduced to the system by Douglas McIlroy.

Cherry, who lived in the Gillette, New Jersey section of Long Hill Township, New Jersey, joined the Northern New Jersey Region chapter of the Sports Car Club of America (SCCA) in July 1967. She raced cars, then served as marshal and handled some administrative duties. She also showed award-winning Doberman Pinschers.

Cherry started as a Technical Assistant (TA) at Bell Labs in 1966, initially working in Acoustics and Speech Research on vocal tract simulation. She received her Masters in computer science from Stevens Institute of Technology in 1969.

Lorinda Cherry (née Landgraf; November 18, 1944 – February 2022) was an American computer scientist and programmer. Much of her career was spent at Bell Labs, where she was for many years a member of the original Unix Lab. Cherry developed several mathematical tools and utilities for text formatting and analysis, and influenced the creation of others.

Cherry was born on November 18, 1944 to John F. and Evelyn K. Landgraf. She had one sister, Carynn Elizabeth. Raised in Verona, New Jersey, she graduated from Verona High School and received a Bachelor of Arts (Mathematics) from the University of Delaware in 1966.
