Two Stanford professor emeriti were named recipients of the National Medal of Science by President Barack Obama on Friday.

Thomas Keith, a professor emeritus of the School of Engineering, and Burton Richter, a professor emeritus in the Physical Sciences, are among the recipients who will receive their medals at a ceremony at the White House later this year. Keith is known for his work on information and system sciences and Richter is a Nobel Prize winner who co-discovered the J/Psi meson. 

“These scholars and innovators have expanded our understanding of the world, made invaluable contributions to their fields and helped improve countless lives,” President Obama said in a press release.

“Our nation has been enriched by their achievements, and by all the scientists and technologists across America dedicated to discovery, inquiry and invention,” he added.
