Dr. Roger Turner | Spectroscopy as Cultural Heritage

The history of spectroscopy is much more than a timeline of landmark papers and advances in instrumentation. Scientific instruments can also be markers that people use to organize themselves and define systems of meaning. What does spectroscopy look like when we view it as a set of cultural practices and social groups? While celebrated figures like Bunsen and Kirchhoff still matter, a social and cultural perspective reveals significant contributions by less famous, and sometimes minoritized, individuals. Women played crucial roles by coordinating groups to create shared community resources, like Clara Smith Craver’s work in building spectra libraries. Communities of spectroscopists were created through short courses like the Fisk University Infrared Spectroscopy Institute founded by James Raymond Lawson and Nelson Fuson. The Science History Institute’s collections offer a window on spectroscopy’s surprising and playful cultural heritage, from a 1954 photo of brawling spectrophotometer salesmen to an aftermarket label warning users about an NMR spectrometer’s “Emotional Crisis Detector.”

Biography

Dr. Roger Turner is the curator of instruments and artifacts at the Science History Institute in Philadelphia. He enjoys translating the history of science for different audiences, from chemists at Pittcon to museum visitors and students of all ages. He has recently written museum displays that situate spectrophotometry as part of the Institute’s temporary exhibits Downstream and Lunchtime. He holds a Ph.D. in the History and Sociology of Science from the University of Pennsylvania
