It is with great sadness that we report the passing of Dr Joe Watson, President of the GASG and former Chair who died recently, following a short illness.
Joe led the GASG as founding Chair from its inception in 1993 until 2015, and during the GASG’s first 22 years, he and his wife Margaret Watson ran the group, including all the administration. When he decided to step down to better enjoy his 'retirement', he continued to co-author and edit several academic books, and remained active on the committee where he was always a passionate advocate for GASG members.
He set the tone for the group and established its enduring and successful mode of operation. His legacy is the friendly, welcoming community that has had an important impact on the development of the UK gas sensing sector. He has left the group in a strong position for the future and we are greatly indebted to him. Our thoughts are with Margaret, his children and grandchildren.

Joe’s education as an electronic engineer included the University of Nottingham and MIT, and in 1959 he started work in the gas detection industry, working closely with Verne Brown to build Enmet, a company supplying medical and industrial gas monitoring equipment. Joe was a Lecturer (later, Senior Lecturer) at Swansea University from 1964 and was a Visiting Professor at the University of Calgary and the Universities of California Davis and Santa Barbara.
He consulted with Figaro and co-authored and edited books on aviation and electronics, including “The Stannic Oxide Gas Sensor, Principles and Applications”.
In due course we will issue a special GASG newsletter to celebrate Joe’s life, including Members’ personal tributes and stories. Please send contributions to [email protected].
