The retired chartered engineer leads the Trades House in Glassford Street until October next year and is to be known as the Third Citizen of Glasgow.
History was made as civil servant Ruth Maltman was appointed the first female assistant, known as Collector, since the house was established in 1605. She is now responsible for overseeing its funds of more than £18million. The organisation gives £600,000 every year to good causes.
Mr Brodie, a former chairman of the Chartered Institution Of Building Services in Scotland said: "I am proud to be a part of the history of our great city and play my role in fostering the good work that the Trades House and Crafts do within Glasgow.
