Australia’s leading authority on English and European antiques for nearly forty decades passed away in his sleep on Tuesday. He reportedly had suffered from early onset Alzheimer's.
Elton paid homage on Instagram, writing:
''I’m so sad that my brilliant friend Martyn Cook has passed away at the young age of 60. Sydney will never be the same. I will miss him very much.''
Cook was the Director of the David Roche Foundation. This was started by the late David Roche, a collector of antiques and fine art.
A good friend of former Prime Minister and collector Paul Keating, Cook's clients included philanthropist Ros Packer.
