David Beer originates from Whitstable in Kent and trained as a teacher at Bishop Otter College, Chichester, where he studied pottery as his main subject.
He started painting at evening class whilst at Corsham, Wiltshire, where he was a Head Teacher. He also attended the St. Ives School of Painting on residential courses during this period and became captivated by St.Ives.
David moved to St.Ives in 1986 and taught for eleven years in Penzance, where he had special responsibility for art in his school and ran in-service art courses for teachers in the area. He was co-ordinator of the education working party for the St.Ives Tate Action Group, before the Tate Gallery opened.
David retired from teaching in 1998 and spent much of the next 12 years painting and running his gallery, Penhaven Gallery in St.Ives, which he opened in 1994.
In 2009 David moved from St.Ives to Saltash, Cornwall and the following year the gallery closed.
In 2012 David moved to Menheniot, near Liskeard where he continues to paint seascapes and landscapes in oil using a palette knife and makes life studies using pastel and acrylics. He exhibits in galleries around the country and has also exhibited in New York.
