Erlang is a general-purpose, concurrent, functional programming language designed by Joe Armstrong, Robert Virding and Mike Williams at Ericsson in 1986 for building fault-tolerant, distributed telecommunications systems. It was released as free and open-source software in December 1998.

Facts
First Released ParadigmMulti-paradigm: concurrent, functional. 2 SignificanceJoe Armstrong summarized the design goal as software that is write once, run forever. Erlang's fault-tolerant, distributed model later powered systems including WhatsApp, well beyond its original telecommunications-switch use. 2 Classification

Associated With
Gleam compiles to and runs on the BEAM, Erlang's runtime.
Base Language For
Direction correction: Elixir compiles to and runs on the Erlang VM (BEAM) and reuses Erlang libraries, not the reverse.
Follows Typing Discipline
Entity-backed identity for the typing discipline value this language already carries as an enum fact, resolved to a concept entity by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The enum fact itself stays on the entity unchanged.

Is Erlang named for mathematician Agner Krarup Erlang or as a syllabic abbreviation of Ericsson Language?
Sources describe the name as presumed by telephony-switch engineers to honor Danish mathematician Agner Krarup Erlang, and also as a syllabic abbreviation of Ericsson Language, the company where the language was created; no single authoritative account settles which motivation, if not both, actually drove the choice.
What would resolve this A primary statement from Joe Armstrong, Robert Virding or Mike Williams, or an Ericsson internal record from the 1980s, definitively naming the intended derivation of the name.
