Wirth was the chief designer of the programming languages Euler ,
Algol W , Pascal ,
Modula-2 , Oberon ,
Oberon-2 , and
Oberon-07 . He was also a major part of the design and implementation
team for the Lilith and Oberon operating systems, and for the Lola
digital hardware design and simulation system. He received the ACM
His book, written jointly with Kathleen Jensen, The Pascal User Manual and Report, served as the basis of many language implementation efforts in the 1970s and 1980s in the United States and across Europe.
His article Program Development by Stepwise Refinement, about the teaching of programming, is considered to be a classic text in software engineering . In 1975 he wrote the book Algorithms + Data Structures = Programs , which gained wide recognition. Major revisions of this book with the new title Algorithms + Data Structures were published in 1985 and 2004. The examples in the first edition were written in Pascal. These were replaced in the later editions with examples written in Modula-2 and Oberon respectively.
His textbook, Systematic Programming: An Introduction, was considered
a good source for students who wanted to do more than "just coding".
Regarded as a challenging text to work through, it was sought as
imperative reading for those interested in numerical mathematics.
In 1992 he published (together with Jürg Gutknecht ) the full documentation of the Oberon OS . . A second book (together Martin Reiser) was intended as a programmers guide.
Main article: Wirth\'s law
In 1995, he popularized the adage now known as Wirth\'s law :
Wirth has reportedly told the joke that, because Europeans pronounce his name properly, while Americans pronounce it as "nickel's worth", he is called by name in Europe and called by value in America.
