History of the LEO(K), Oegstgeest

LEOK at Oegstgeest

After his return to the Netherlands in 1946, jhr. ir. J.L.W.C. von Weiler, who was incorporated into the Royal Netherlands Navy during his stay in England, continued his radar development and consultancy work as Head of the Development and Test Division of the Navy Radio Service, Oegstgeest, Netherlands. In 1950, this department consisted of 25 persons and became the Laboratory for Electronic Developments (LEO). LEO was aimed at filling the immediate needs of the Royal Netherlands Navy with operational equipment for radio communication and radar. In 1955, the LEO activities were extended with activities for both the Royal Netherlands Army and the Royal Netherlands Air Force. For that reason, the laboratory name was changed to the Laboratory for Electronic Developments for the Armed Forces (LEOK). The LEO (and later LEOK) shared a building with the Navy Electronic Optical Works (MEOB) in Oegstgeest.

In 1958, the LEOK moved into a new two-story building, which created space for research in the field of radar systems, training and simulation equipment.
