Speakeasy (computational environment)

Speakeasy was a numerical computing interactive environment also featuring an interpreted programming language. It was initially developed for internal use at the Physics Division of Argonne National Laboratory by the theoretical physicist Stanley Cohen. He eventually founded Speakeasy Computing Corporation to make the program available commercially.

Speakeasy is a very long-lasting numerical package. In fact, the original version of the environment was built around a core dynamic data repository called "Named storage" developed in the early 1960s, while the most recent version has been released in 2006.

Speakeasy was aimed to make the computational work of the physicists at the Argonne National Laboratory easier.
