Lady Philippa Scott sat as part of my environmental series of heads in early 2007. The Wildfowl and Wetlands Trust – that she and husband Peter Scott had been so instrumental in founding – have just taken delivery of a bronze of the terracotta head, which will be unveiled in summer 2011. This will commemorate her life and work, after she passed away in 2010 at the age of 91. Click on the picture to see The Guardian’s obituary.
