The Technical Study Stores are part of the Hungarian Museum of Science, Technology and Transportation, located in District XI. Although its name might not inspire an outburst of excitement, it’s a great source of hidden historical treasures, and the forgotten artefacts of the country’s technological heritage. There is a wide range of exhibited objects from tiny cameras used by secret agents to enormous telescopes, or invaluable world clocks. Ányos Jedlik’s special dynamo (a dynamo powered by electricity) and József Petzvál’s objective system are preserved in the Technical Study Stores besides such unique objects as the Remington N 1 typewriter, which is the world’s first typewriter produced in a factory; the manually operated mechanical vacuum cleaner, which is made of wood; and the prototype of László Bíró’s ball point pen, which was a world patent as well.
