History

Established in 1986 as German Social Science Infrastructure Services, GESIS originally consisted of the three independent institutes:

Social Science Information Centre in Bonn,
Central Archive for Empirical Social Research in Cologne, and
Centre for Survey Research and Methodology in Mannheim.

In 2007, the three GESIS institutes merged into one. In November 2008, GESIS added "Leibniz Institute for the Social Sciences" to its name in order to emphasize its membership in the Leibniz Association.
In November 2011, GESIS Bonn and Cologne were merged into one location in Cologne.

WikiWho

WikiWho, developed by Fabian Flöck and Maribel Acosta and hosted by GESIS, "parses the complete set of all historical revisions in order to find out who wrote and/or removed and/or reinserted which exact text at token level at what revision". WhoColor and whoVIS are in development. Researchers developing and using WikiWho, also investigated the Gamergate. In 2021, Fabian Flöck planned to leave GESIS and shut down WikiWho sometime in 2022, however, a Wikimedia Foundation software engineer is working to migrate the infrastructure. Wikimedia Foundation, Community Tech Team has released Who Wrote That?, a browser extension, for Mozilla Firefox and Chromium-based browsers using WikiWho. Contropedia is a related "platform for the real-time analysis and visualization of such controversies in Wikipedia".
