A mural honoring Joseph Priestley, the scientist who discovered oxygen 250 years ago, will be unveiled in Calne to mark the anniversary of his groundbreaking discovery. Born on March 13, 1733, Priestley is recognized as one of the founders of modern chemistry due to his contributions to experimental science.
In 1773, the Earl of Shelburne enlisted Priestley to serve as an intellectual companion, tutor to his children and librarian at Bowood House in Wiltshire. It was there that Priestley conducted his scientific experiments using a “burning lens,” which he focused sunlight on a sample of mercuric oxide in an inverted glass container placed in a pool of mercury. This resulted in the discovery of oxygen.
The artwork for the mural will be created by local artist Oli Knowles, with plans to start in June and have it completed by August 1st – the anniversary of Priestley’s historic breakthrough. The mural will depict the implements used in Priestley’s experiment and serve as a way to brighten up Calne and keep it clean.
The Calne Clean Up Crew, a local charity, is behind the project. They have received positive responses from painting murals and how it sparks curiosity among the community leading to further discoveries.
