[3] Prendergast moved to the Slade School of Fine Art in 1964, where he studied under Sir William Coldstream, Francis Bacon, and Euan Uglow.
[4] Prendergast taught part-time in a school for one year after leaving the Slade, and then studied for a Master's degree at Reading University with Terry Frost and Claude Rogers.
He specialised in paintings of the Penrhyn slate quarry, which he described as "the biggest man-made hole in Europe, like Bruegel's The Tower of Babel, but in reverse", and of Snowdonia.
After suffering from poor health in 2006, he died suddenly from a heart attack while walking with his wife near his home in Deiniolen, near Caernarfon in Gwynedd.
In 2013 Richard Cork's biography of the artist, The Art of Peter Pendergast, was published by Lund Humphries, with an introductory essay by Prendergast's old friend, Mike Knowles.
