mercury vapor lamp turned up in the collection of spectroscopist William
F. Meggers, in the Niels Bohr Library's archives. A note in Meggers's
hand on the wooden case says it was blessed by Pope Pius XII in 1952.
We have donated the lamp, with other artifacts from the Meggers collection,
to the archives and museum of the National Institute of Standards
and Technology. Meggers was head of the Spectroscopy Division of what
was then the National Bureau of Standards from 1919 to 1958. Our Archivist,
Katy Hayes, is now completing the archival processing of the Meggers
papers. In July she gave a brief presentation on the collection to
the Standards Alumni Association. The date inscribed on the wood is
7 Sept. 1952.
