International Council for Laboratory Animal Science
research-related entity
The International Council for Laboratory Animal Science (ICLAS) is an international non-profit organization dedicated to the worldwide promotion of ethical principles, scientific responsibilities, and welfare in the use of laboratory animals for research and education.
Originally established as the International Committee on Laboratory Animals (ICLA) in 1956, ICLAS activities focus on:
education and training for those working with laboratory animals,
harmonisation of guidelines on the care and use of laboratory animals,
the enhancement of laboratory animal quality,
promoting the continuing development of LAS worldwide through its regional committees and scientific meetings.
Governance
ICLAS's policy-making body is its Governing Board (GB), which consists of volunteer representatives of National, Scientific, Union and Institutional ICLAS members who are elected every four years at the ICLAS General Assembly.
Funding
ICLAS's funds come mainly from annual ICLAS member fees, which vary according to the size of the organization and membership category. Other income sources are periodic donations and sponsorships, particularly for ICLAS training programs, from companies, organizations and foundations operating in the field of laboratory animal science (LAS).

History
Growth in the number of animals used in research
Following the publication of Charles Darwin's "On the Origin of Species" in 1859, and Claude Bernard's book on vivisection in 1865, by the late 19th century, animal research had become the predominant method of laboratory investigation.
The early 20th century saw an expansion of laboratory animal use in vaccine development. In 1908, the poliovirus was identified as the cause of polio, and in the 1930s, mass vaccination campaigns using diphtheria toxoid began in several countries.
Animals were also used extensively in the development of drugs, notably Frederick Banting's revolutionary treatment of diabetes using insulin isolated from dogs in 1921, and Alexander Fleming's discovery of penicillin in 1928, which led to extensive testing on mice. This period was also marked by an explosion of new synthetic chemistry, which necessitated large-scale pharmacological testing using animals as human surrogates.
Begin with the source’s own compact description: “International Council for Laboratory Animal Science” is research-related entity. The dossier treats that line as a proposition to test through International, Council and Laboratory, not as a finished interpretation.
Why this record matters
The phrase “research-related entity” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q114556696. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1956, 2026, 1859 and 1865.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
How to read it
