Dacta was an original LEGO theme from 1960 to 2003 that deals with all things that can be used with educational facilities, such as DUPLO and TECHNIC. Dacta was later replaced by the LEGO Education theme. Sets in the Dacta product line were exclusively developed for usage in younger aged schools so the sets typically contain a large amount of pieces for playing and learning in groups. The sets were designed to contain a higher number of bricks and elements at a lower cost.
1965 LEGO Sets
By 1965, LEGO employed more than 600 people as production scaled rapidly. Packaging was redesigned to feature only buildable models, improving clarity and consistency. In North America, Samsonite introduced the first LEGO gears—designed in Billund by Knud Møller Kristiansen—allowing mechanical motion and simple transmissions. Though initially exclusive to the U.S. and Canada, these parts marked LEGO’s first step toward functional construction.
