National Institute of Standards and Technology Campus, Maryland

Large campus with numerous offices and laboratory buildings. There is also a museum on site, although it is not open to the public. Founded in 1901 as the National Bureau of Standards, it was renamed the National Institute of Standards and Technology (NIST) in 1988. NIST has produced reference standards for units of electricity, length, mass, light, time, and temperature, as well as having been involved in the research, design, and creation of a host of innovations, including the radio direction finder antenna, the proving ring, the world's first atomic clock, the world's first internally programmed digital computer, the panoramic X-ray, the first digital image, the first DNA profiling standard, and assorted internet encryption standards. NIST is also the source for over 1300 different Standard Reference Materials, for use in various quality control and measurement applications.
