Henry Cavendish is given credit for discovering hydrogen in 1766. While others, such as Robert Boyle, may have produced hydrogen gas earlier (as early as 1671), Cavendish was the first to identify it as a distinct element and characterize its properties, notably its combustion to form water.
A Deeper Dive into the Discovery
Several sources suggest that hydrogen gas was produced unintentionally by others before Cavendish's work. These include:
- Robert Boyle (1671): Historical accounts indicate Boyle may have generated hydrogen gas during experiments with iron and acids, though he didn't recognize its unique nature. [Source: Horizon Educational, Wikipedia]
- Paracelsus (16th Century): Some sources attribute an unwitting discovery to Paracelsus, a Swiss alchemist. [Source: RSC Periodic Table]
- Early Scientists: Scientists had been producing hydrogen for years before it was formally recognized as an element. [Source: PubChem]
However, it was Henry Cavendish who systematically studied the gas, determining its properties and recognizing it as a distinct substance. He observed its flammability and, crucially, identified the product of its combustion as water. This led to the naming of the element, "hydrogen," which translates to "water-former."

Cavendish's meticulous work established the foundation for our understanding of hydrogen as an element. Although earlier researchers may have encountered the gas, it was Cavendish's detailed investigation that secured his place in history as the discoverer of hydrogen.
