John Frederic Daniell
William Grove

Correct Answer: Alessandro Volta

Explanation:

Given data & context

Seeking the originator of the first practical battery.

Reasoning
Alessandro Volta created the voltaic pile (1800), the earliest continuous source of electric current. Later chemists improved specific cell designs (e.g., Daniell cell), but Volta's device is the first battery.

Common pitfalls
Attributing the invention to Galvani due to his experiments with frog muscles; he did not invent a working battery.

Final Answer
Alessandro Volta.
