Early Railway Chemistry and Its Legacy by Colin A. Russell and John A. Hudson (review)

Chemists and chemistry do not strike most of us as immediately relevant to the development of railways, but these authors make a good case for revising that judgment. Colin Russell, who sadly has just died, and John Hudson are highly respected historians of chemical theory and practice, au fait with technical practices and the rise of the industrial chemist, with the history of technical education, and with the records of chemical societies both learned and professional. They bring this expertise to their investigation of railways in Britain, vindicating their belief in the ubiquity of chemistry�a science often overlooked as unglamorous.
