Reference excerpt

Anselm Stanley Dissanaike (1925–2015) was a distinguished Sri Lankan parasitologist renowned for his significant contributions to medical science and parasitology. In recognition of his scientific achievements, the University of London awarded him a Doctor of Science (DSc) in 1966. Two parasite species were named in his honor: Bilorchis dissanaikei, a trematode, and Plasmodium dissanaikei, a malarial parasite of parakeets, the latter discovered by one of his former students in London.

Early life and education Stanley Dissanaike was born on 29 October 1925 in Colombo, Sri Lanka. He received his early education at Richmond College, Galle, and St. Peter's College, Colombo. He later attended the University of Ceylon, where he earned a BSc in Zoology with first-class honors, specializing in parasitology. He pursued further studies in medicine, graduating with distinction and receiving several first-class honors and medals from the Faculty of Medicine, University of Ceylon. In 1954, he completed his PhD at the London School of Hygiene and Tropical Medicine, under the supervision of Professor Cyril Garnham, FRS.

Academic and professional career

University roles Stanley held several academic and administrative roles throughout his career. He served as the Dean of the Faculty of Medicine at the University of Ceylon (Colombo) from 1967 to 1970 and was the Chair in Parasitology from 1964 to 1972. Later, he joined the University of Malaya in Kuala Lumpur, where he held the Chair in Parasitology.

Research contributions Dissanaike's research focused on identifying parasites of zoonotic importance and elucidating the life cycles of several parasites in Sri Lanka and Malaysia. His work highlighted the role of parasites in crossing species barriers, a concept that remains crucial to modern infectious disease research. In 1978, he joined the World Health Organization's Special Program for Research and Training in Tropical Diseases (TDR) in Geneva, where he contributed to global health initiatives. Even after his retirement, he remained an active member of the WHO Expert Committee on General Parasitology.

Recognition and honors Doctor of Science (DSc): Awarded by the University of London in 1966. Fellowship of the Royal College of Pathologists (UK): Conferred in 1977. Professor Emeritus: Conferred by the University of Colombo in 1995.

Personal life Stanley's family included notable academics and professionals. His elder brother, Ben Dissanaike, was a former President of the Institute of Chemistry in Sri Lanka and Head of the Government Analysts' Department. His younger brother, Professor George Dissanaike, was a physicist and a respected academic.

Legacy Stanley's contributions to parasitology are immortalized through the naming of two parasites:

Bilorchis dissanaikei (a trematode) Plasmodium dissanaikei (a malarial parasite of parakeets)

Worked examples

Example 1 — a first encounter with Stanley Dissanaike

Start with the simplest possible case. Write down what Stanley Dissanaike claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stanley Dissanaike before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stanley Dissanaike ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stanley Dissanaike

In research: Stanley Dissanaike appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Stanley Dissanaike in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Stanley Dissanaike is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1925 births, 2015 deaths, Academic staff of the University of Colombo, so understanding it makes those chapters shorter.
In everyday life: Look for Stanley Dissanaike outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
