Research into diatoms commenced with the advent of the light microscope in the early 19th century and progressed to an advanced state in the 1950s. Since then the application of many new techniques, in electron microscopy, biochemistry, molecular biology and sediment dating, to name a few, has provided additional stimulus to the study of these micro-organisms which play a vital role in marine and freshwater ecosystems. Their siliceous cell walls are amongst the best preserved micro-fossils and thus feature greatly in micro-palaeontology and its applied aspects, such as climate interpretation. Ease of culture has also led to considerable use of diatoms in physiological, cell biological and biochemical studies.
Until 1970 there was no focal point for diatomists worldwide although they have always been busy correspondents and well-informed of each other’s contributions. In 1970 a gathering together of 15 participants in a symposium on recent and fossil marine diatoms was organised by Reimer Simonsen at Bremerhaven, Germany. Also present were:
George Andrews (U.S.A.), Leopold Benda (Germany), Lloyd Burckle (U.S.A.), Gerhard Drebes and Johannes Gerloff (Germany), Grethe Hasle (Norway), Norman Hendey (England), Taro Kanaya (Japan), Dietrich König (Germany), Robert Ross (England), Hans-Joachim Schrader (Germany), Alain Sournia (France), Sam VanLandingham and Walter Wornardt (U.S.A.).
This was the first of a series of biennial symposia that visited London (UK), Kiel (Germany), Oslo (Norway) and Antwerp (Netherlands) before the scope of the symposium was broadened to include work with non-marine diatoms at Budapest (Hungary). By this time the number of people attending the meetings had increased some ten-fold and subsequent symposia were organised at Philadelphia (U.S.A.), Paris (France), Bristol (UK), Joensuu (Finland), San Francisco (U.S.A.), Renesse (Netherlands), Maratea (Italy), Tokyo (Japan), Perth (Australia), Athens (Greece), Ottawa (Canada), Miedzyzdroje (Poland), Listvianka (Siberia), Dubrovnik (Croatia), St Pauls (USA), Ghent (Belgium), and Nanjing (China).
Surprisingly, in view of the long history of research, there was never an International Society serving all diatomists whatever their interest until the Bristol meeting in 1985 where the ISDR was formed and its first officers elected. At this meeting it was also decided that the biennial business meeting of the society would take place at the biennial symposia which would from that time be organised through the society. At Bristol it was also decided that the society would support its own journal which would be floated and published in two parts annually by Biopress with Frank Round as the executive editor. In 2011, the ISDR transferred publication of Diatom Research to Taylor and Francis. The journal is published in 4 online issues (2 printed) per year. Building on the reputation established with Biopress, the journal provides a focus for the continuing development of all fields of research on diatoms. It also draws together much work which had been scattered, often in relatively inaccessible publications.

The Society shall be called the International Society for Diatom Research.
The object of the Society shall be to promote for the benefit and education of the public all branches of diatom studies throughout the world.
In furtherance of the above object but not further or otherwise the Society shall have the following powers:
- To facilitate the exchange of information amongst diatomists by organizing, in cooperation with other scientific bodies, a biennial conference and publishing the proceedings of the conference;
- To publish the results of diatom research in a journal entitled Diatom Research;
- To raise funds and to invite and receive contributions from any person or persons whatsoever by way of subscription, donation, and otherwise, provided that the Society shall not undertake any permanent trading activities in raising funds for its charitable objects;
- To do all such other lawful things as are necessary to attain the above objects
The membership shall consist of Honorary Members and Ordinary Members.
- Honorary members shall be diatomists who have rendered outstanding service either to the study of diatoms or to the Society. They shall be nominated by the Council and elected at the biennial General Meeting (hereafter the General Meeting). They shall pay no subscription but shall have the same privileges as Ordinary members;
- Ordinary membership shall be open to any individual with an interest in diatoms. Ordinary members shall be admitted to the Society on payment of their first annual subscription. They shall be entitled to vote at meetings and to receive the journal Diatom Research;
- Council may terminate the membership of any member whose activities are considered to bring the Society into disrepute or be prejudicial to its objectives provided that that member shall have the right to attend and be heard by the Council before the decision is made.
