William Clyde Martin

William Clyde Martin Jr. (November 27, 1929 – September 15, 2013) was an American physicist. After receiving his Ph.D. degree from Princeton University in 1956, he joined the staff of the National Bureau of Standards (NBS: now NIST, the National Institute of Standards and Technology), where he was employed until his retirement in 1998. As Chief of the NBS Atomic Spectroscopy Section (and its successor organizations) from 1962 to 1998, he led the development of its reference data resources on the spectra of rare-earth elements, substantially increased its coverage of highly excited and ionized species, and pioneered the publication of NIST Standard Reference Data on the internet. -Wikipedia
