In 1808, Sir Humphrey Davy discovered barium, boron, calcium and magnesium. According to Jefferson Lab, he also discovered potassium and sodium in 1807. While he discovered boron with other scientists, such as Joseph-Louis Gay-Lussac and Louis-Jaques Thénard, he discovered the other elements by himself. It is worth noting that many scientists discovered the same elements at the same time as scientific discovery gained momentum.

Sir Humphrey Davy was a British chemist who played a rather pivotal role in the discovery of some of the most common and useful elements in the periodic table. Although he was initially an apprentice to an apothecary and surgeon, his interest in chemistry grew quickly. Later, his main area of work, from which these discoveries were made, was electrochemistry. Independently from other pioneer electrochemists and discoverers, including Gay-Lussac and Thénard, Sir Davy isolated magnesium, calcium, barium sodium, potassium, strontium and boron between 1807 and 1808. Due to his role in these discoveries and the subsequent rise in industrial safety through the Davy lamp, Sir Humphrey gained recognition for these discoveries despite the fact that other scientists played equally significant roles. Sir Humphrey Davy is mainly remembered for his discoveries and contributions to electrochemistry and the chemistry of alkali metals, especially through the many lectures he organized.
