2009 – Judah Levine

Judah Levine was awarded the Time Lord Award at ITSF 2009.

Judah Levine has been a physicist at the National Institute of Standards and Technology (formerly called the National Bureau of Standards) since 1969. He has worked on many aspects of time and frequency metrology during that time and designed and implemented the software that operates the NIST ensemble of atomic clocks and which is used to realize UTC(NIST), the official time scale for civilian applications in the United States.

He designed and implemented the hardware and software that are used to realize the NIST ACTS service, which provides time messages over dial-up telephone lines. He also designed and implemented the ensemble of time servers that distribute time over the Internet in a number of different formats. These servers currently receive about 40,000 requests per second.

In addition to his work on time and frequency metrology at NIST, Dr. Levine has also worked with students at the University of Colorado at Boulder on a number of problems of geophysical interest, including a study of the fault-zone dynamics of Southern California and an investigation of the uplift of the caldera in Yellowstone National Park, Wyoming.

Judah was presented with an Armillary Sphere.
