The history of Van Swinden
VSL (short for ‘Van Swinden Laboratory’) is named after Jean Henri van Swinden (1746-1823), a lecturer in Franeker and later in Amsterdam. Van Swinden was part of an international committee to define the metre, after which he applied himself to getting the metric system introduced into the Netherlands. He was also the person who first introduced the metre (a platinum rod) in 1799. An important follow-up to this was the Metre Convention of 1875, in which it was agreed at international level for the first time that countries would start to keep to a single system of weights and measures.
The above developments led to the introduction of the SI system in 1960. It actually took until 1999 before many countries signed the Mutal Recognition Arrangement (MRA) thus indicated they would accept each other’s national standards and associated measurement results.
