The collection consists of around 275 cars and other vehicles. It was founded in 1934 with the purchase of a 20-year-old
Dodge by Dodge importer Pieter Louwman, the father of the current owner. In 1969, the collection of Mr. Geerlig Riemer was added. Riemer was also founder of the Institute for Automotive and Management (IVA) in
Driebergen. The building which used to house Riemer's collection has since been used as a practical center for the IVA. In 1969 the collection was moved to
Leidschendam to the newly opened National Automobile Museum. In 1981 the museum was moved to a new location on the property of importer Louwman & Parqui in
Raamsdonksveer. On 18 April 2003 the name "Louwman Collection" was adopted. On 3 July 2010 the current museum in The Hague, named Louwman Museum, was opened by
Queen Beatrix of the Netherlands, whose former home
Huis ten Bosch neighbours the museum. The current owner of the collection is Evert Louwman, the Dutch importer of
Lexus,
Toyota, and
Suzuki. ==Building==
