The death of Jock Stewart MBE, in his 81st year and a former director of BSRIA, has been announced by the association.
Mr Stewart joined BSRIA in 1964 to run its Heating and Air Conditioning Division, becoming head of its Technical Division in 1973.
Born in New Zealand in 1931, he attended the University of Durham before working in his country’s Ministry of Works.
Mr Stewart was involved with many organisations and chaired several groups concerned with the development of technical publications and was a member of the CIBSE technical publications committee from 1973 to 1978.
He was awarded the Silver Medal of the institution and was awarded the MBE in recognition of his services to the industry.
BSRIA personnel including Mike Smith, engineering director, and Andrew Eastwell, chief executive officer, paid tribute to Mr Stewart.
“He was one of the best bosses I ever worked for. He had a very sharp mind and a huge understanding of the industry – both technical and commercially. He never spoke ill of anybody and was always encouraging,” said Mr Smith.
Mr Eastwell said: “It was Jock who interviewed me for a junior engineering post in 1975 and I had the privilege of working for him for many years. He exemplified the things that make a good engineer and colleague - thoroughness, patience and generosity and BSRIA and owes a great deal to his service.”
