• A new exhibition at the Dulwich Picture Gallery explores the truth behind 18th century gossip suggesting 17th century Dutch artist Philips Wouwerman was a plagiarist. True Crime: The Case of Philips Wouwerman looks at claims the painter, who created more than 600 paintings over his career, stole the drawings of the dead artist Pieter van Laer and subsequently used them for his own works. The display features works by Wouwerman and Van Laer as well as expert testimony from the past and present. It’s the first in a series of displays – Unlocking Paintings – which have been devised by the recently appointed curator Helen Hillyard to present new perspectives on the Gallery’s collection. Can be seen until 21st August. For more, follow this link.

• A self-taught Victorian physicist, Oliver Heaviside, has been commemorated with an English Heritage Blue Plaque at his former home in Camden Street. The property is where the young Victorian scientist, who had been left almost entirely deaf after suffering scarlet fever in childhood, continued with his self-education after leaving school at 16 and where he later worked on his ground-breaking interpretation of James Clerk Maxwell’s Treatise on Electricity and Magnetism. Heaviside played a key role in the development and advancement of electrical communications and was even name-checked in Cats where a line referring to “the Heaviside layer” is a reference to his discovery of a reflective layer in the upper atmosphere which allowed radio waves to be ‘bent’ around the earth. For more, see www.english-heritage.org.uk/visit/blue-plaques/.
