From Prof. Peter Morris:
"I regret to inform you that Professor Colin Russell of the Open University and Cambridge University passed away at home on Friday 17th May. Well-known for his work on the history of valency and the chemical industry, and for his biography of Edward Frankland, Professor Russell was Chair of the RSC Historical Group in the 1980s and President of the BSHS in 1986-8. He was also a member of the Council of the RSC between 1999 and 2002. He made the Open University a major centre for the history of chemistry between the 1970s and 1990s. He filmed several industrial processes for an Open University course in the early 1970s, including the last working lead chamber acid plant just before it was demolished. After much negotiation, he microfilmed the Edward Frankland correspondence, at that time unknown to scholarship and in private hands, thereby making available to historians of chemistry."
Prof. Russell will be very greatly missed.
