The NCTU Seal


The NCTU seal first appeared during the 1920s. At the time, the seal only contained the school’s Chinese and English names, the motto, the gear, and the outer ring. After 1926, when the motto was eliminated and the anvil, hammer, rings, books, and founding date of the school were added, the general form of the seal was largely fixed. Later on, only slight changes of the outer ring, the number of teeth in the gear, the shapes, and the school’s name on top were added. The changes of the meanings of the seal are explained in detail below.
