Judah Levine received the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society Rabi Award on July 24 during a joint symposium on time and frequency held in Prague, Czech Republic. Participants included the IEEE-International Frequency Control Symposium (IFCS), the IEEE-International Ultrasonics Symposium (IUS), the IEEE-International Symposium on the Applications of Ferroelectric (ISAF) and the Piezoresponse Force Microscopy and Nanoscale Phenomena in Polar Materials (PFM), and the European Frequency and Time Forum (EFTF).

Levine was cited for his outstanding contributions to the field of precise time keeping and time transfer, including pioneering research and development of time transfer, network time services, and the design of better time scales. His award cited clear tutorial writings that have made these advances open to the world community.

Much of Levine’s work is now used worldwide in the generation and dissemination of precision timing. Levine has authored more than 100 articles on his research, including review articles on atomic clocks and time scales, network and internet timing, time and frequency transfer methods, time and frequency transfer through satellites, and time and frequency metrology.

Levine was nominated for the award by Nobel Laureate John Hall and NIST physicist Andrew Ludlow, who received his Ph.D. from the University of Colorado under the direction of Jun Ye. The nomination was seconded by Tom O’Brian, Chief of NIST’s Time-and-Frequency and Quantum-Physics Divisions.

O’Brian noted that Levine’s work has directly impacted both the U. S. technology infrastructure and economy. Levine pioneered network time distribution in the earliest days of the Internet. His Internet Time Service (ITS) now provides more than 10 billion automated synchronizations per day. The ITS is currently built into such commercial computer operating systems as Windows, Mac OS, and commercial Linux. It is also the primary source for time stamping billions of dollars worth of electronic financial transactions that occur daily on the New York Stock Exchange, NASDAQ, and the American Stock Exchange.

Levine is a Fellow of the American Physical Society and has received many awards including two Department of Commerce Gold Medals, the Presidential Rank Award, and the NIST Allen Astin Award for his pioneering of network time distribution and his many invited review articles on time keeping and time transfer. He won the well-deserved Time Lord Award from the 2009 International Telecom Sync Forum.
