The seal of the University of Houston, officially adopted in 1938, is the coat-of-arms of General Sam Houston, who claimed descent from a Norman knight, Sir Hugh. The simple escutcheon in the center of the seal consists of checkered chevrons denoting nobility, and three martlets, gentle lowland birds symbolizing peace and deliverance. A winged hourglass is above the shield and surmounting this, the motto, “In Tempore” (In Time). Greyhounds were placed at the sides to indicate the speed in giving aid.
As the most formal and ceremonial official mark of the University, the UH Seal may only be used by the Office of the President and Office of the Provost. Doing so helps retain the seal's integrity for official communications from these offices and designated ceremonies, such as commencements.
