APL (A Programming Language) is an
array programming language based on a notation invented in 1957 by
Kenneth E. Iverson while at
Harvard University. It originated as an attempt to provide consistent notation for the teaching and analysis of topics related to the application of computers. Iverson published his notation in 1962 in a book titled A Programming Language, and APL got its name from the title of this book. In 1964, a subset of the notation was implemented as a programming language. Iverson received the
Turing Award in 1979 for his work.
