Vote: | By the time (the Leaning Tower of Pisa) was 10% built, everyone knew it would be a total disaster. But the investment was so big they felt compelled to go on. Since its completion, it cost a fortune to maintain and is still in danger of collapsing. There are no plans to replace it, since it was never needed in the first place. I expect every installation has its own pet software which is analogous to the above. |

Vote: | T]he initial motive for developing APL was to provide a tool for writing and teaching. Although APL has been exploited mostly in commercial programming, I continue to believe that its most important use remains to be exploited: as a simple, precise, executable notation for the teaching of a wide range of subjects. |

Vote: | The thesis... is that the advantages of executability and universality found in programming languages can be effectively combined, in a single coherent language, with the advantages offered by mathematical notation. |

Biography
|
Kenneth Eugene Iverson (17 December, 1920, Camrose, Alberta/Canada –October 19, 2004,Toronto, Ontario/Canada) was a computer scientist most notable for developing the APL programming language. He was honored with the Turing Award in 1979 for his contributions to mathematical notation and programming language theory.
The Iverson Award for contributions to APL was named in his honor.
He received his Bachelor's degree in Mathematics and Physics in 1951 from Queen's University, Kingston in Canada. At Harvard University, he received his Master's degree in 1951 in Mathematics and his Ph.D. in Applied Mathematics in 1954.
As an assistant professor at Harvard, Iverson developed a mathematical notation for manipulating arrays that he taught to his students. In 1962, he began work for IBM and working with Adin Falkoff, created APL based on the notation he had developed. He was named an IBM Fellow in 1970.
He later developed the J programming language,
