Notable usage in science: The most well-known association with the name is the Daniell cell, an early practical electrochemical cell developed by John Frederic Daniell (1799–1845). The Daniell cell paired a copper electrode in copper sulfate solution with a zinc electrode in zinc sulfate solution, separated by a porous barrier. It produced a steadier voltage than many earlier galvanic cells and helped establish methods for measuring electrical potential. The Daniell cell is regarded as a milestone in the history of electrochemistry and contributed to the transition from speculative to experimental approaches in the field.

People and cultural presence: Beyond John Frederic Daniell, the surname Daniell has been used by other individuals across various disciplines. While not all bearers of the name are connected to the Daniell cell, the term remains a historical reference in electrochemistry and science literature. The name continues to appear in genealogical and biographical contexts, reflecting its English-origin roots and enduring presence in the Anglophone world.
