Prior to joining Haymarket, Brown ran his own fashion manufacturing business, Gavin Brown Leathers, before joining forces with June Barker to form independent exhibition business, Barker Brown.
The pair went on to launch the first ever Clothes Show Live in 1989, after being approached by the BBC.
When Haymarket acquired Clothes Show Live in 2000, Brown joined the company to lead and develop its successful portfolio of live events, including Autosport International and Cereals.
Brown was instrumental in a number of milestones for Haymarket’s exhibitions portfolio, including a partnership with Media 10 to bring Britain & Ireland's Next Top Model Live to Clothes Show Live in 2012, as well as the management buyout of BBC Haymarket Exhibitions two years ago.
Kevin Costello, chief executive of Haymarket Media Group, said: "Gavin had a real love of the exhibition business and his roots in the fashion industry stayed with him all his working life. The legacies of which were his ever-stylish appearance and his keen trader’s eye for a deal.
"Gavin’s warmth, good humour and optimism were much cherished by current and former colleagues and by industry contacts around the world. Our thoughts and deepest sympathies are with Gavin’s family."
