Advanced Computer Techniques
computer software company

Advanced Computer Techniques (ACT) was a computer software company most active from the early 1960s through the early 1990s that made software products, especially language compilers and related tools. It also engaged in information technology consulting, hosted service bureaus, and provided applications and services for behavioral health providers. ACT had two subsidiaries of note, InterACT and Creative Socio-Medics.
Both writer Katharine Davis Fishman, in her 1981 book The Computer Establishment, and computer science historian Martin Campbell-Kelly, in his 2003 volume From Airline Reservations to Sonic the Hedgehog: A History of the Software Industry, have considered ACT an exemplar of the independent, middle-sized software development firms of its era, and the Charles Babbage Institute at the University of Minnesota has also viewed the company's history as important.
Founding and early history
Advanced Computer Techniques was founded in New York City in April 1962 by Charles P. Lecht. It had an initial capitalization of $800, one contract, and one employee. Lecht, in his late twenties at the time, was a mathematician and entrepreneur whose involvement with the computer industry dated back to the early 1950s, including stints at IBM and the MIT Lincoln Laboratory.
The new firm's first job was fixing a language compiler on the UNIVAC LARC computer, which was being used by the United States Navy. UNIVAC awarded a $100,000 contract for the work; Lecht hired some programmers and the company's first office was in former servant quarters atop the Plaza Hotel. The firm was one of 40–50 software companies started in the early 1960s, many of which would go on to be forgotten.
This brief starts where responsible research should: with the source description of “Advanced Computer Techniques” as computer software company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as computer software company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 28, 2026. The linked authority identifier is Q17985413. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1981, 2003 and 1962.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
