In 1774, Joseph Priestley made a groundbreaking discovery that would change the course of modern chemistry. While working as a librarian at Bowood House in Wiltshire, he discovered oxygen through an experiment using a “burning lens” and mercury. Now, 250 years later, Priestley will be honored with a mural in Calne to mark the anniversary of his discovery.
Priestley, born on March 13, 1733, is widely recognized as one of the founders of modern chemistry due to his contributions to experimental science. In 1773, the Earl of Shelburne enlisted him to serve as an intellectual companion, tutor to his children, and librarian at Bowood House. It was there that he conducted his scientific experiments and made the historic discovery of oxygen.
The mural will be created by local artist Oli Knowles and will depict the implements used in Priestley’s experiment. The artwork is set to begin in June and be completed by August to coincide with the anniversary of Priestley’s discovery. This project marks the fifth mural in Calne and serves as a way to brighten up the town while keeping it clean. Cath Crofts, a volunteer with the charity behind the project, expressed excitement about the positive responses they have received from painting murals and how it sparks curiosity and leads to further discovery among members of the community.
