Barry Philip Devenish – Founding Member

16 March 1953 – 28 April 2017

We are deeply saddened by the death of one of our founding members but most of all our dear friend, Barry.

He will be remembered for his brilliant mind, fast wit and quiet nature.

His esteemed input as PR Engineer will be missed. Delusch played a large role in Barry’s life and brought him much pride and joy. It is our intention to honour his wish that Delusch continues to grow from strength to strength.
