Honoring a Pioneer in Chemistry: A Mural Celebrating the Discovery of Oxygen by Joseph Priestley in Calne

Joseph Priestley, the scientist who made a groundbreaking discovery of oxygen 250 years ago, will be honored with a mural in Calne to mark the anniversary of his breakthrough. 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 here that Priestley conducted his scientific experiments using a “burning lens” to focus 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.

Now, local charity Calne Clean Up Crew is behind the planned mural which will have a scientific theme depicting the implements used in Priestley’s historic experiment. The artwork will be created by local artist Oli Knowles, with plans to start in June and have it completed by August – just in time for the anniversary celebration.

Cath Crofts, a volunteer with the charity expressed excitement about their positive responses from painting murals and how it sparks curiosity among members of the community leading them to further discoveries. This project will be the fifth mural in Calne and serves as a way to brighten up the town while keeping it clean.
