The Discovery of Barium
Barium was discovered by in 1774 by Carl Scheele and extracted by Sir Humphry Davy in 1808.
Carl Wilhelm Scheele
Carl Scheele (9 December 1742 – 21 May 1786) was a German chemist who made a number of important chemical discoveries before many others but was rarely given the credit for his findings. For instance, although Scheele discovered Oxygen Joseph Priestley published his findings first so was given the credit. Carl Scheele also identified molybdenum, Tungsten, barium, hydrogen and Chlorine before Humphry Davy and other scientists.

Sir Humphry Davy
Sir Humphry Davy (1778-1829) isolated Sodium, Lithium, Potassium, barium, strontium, and calcium by means of electrolysis; demonstrated the elementary nature of chlorine; invented the safety lamp; discovered the stupefying effects of nitrous oxide.

Antoine Lavoisier was famous for his care in quantitative experiments, for demonstrating the true nature of combustion, for introducing system into the naming and grouping of chemical substances. Lavoisier was executed in 1794 during the French Revolution.

What is Barium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri Mendeleev knew in his day in his day but still all fitting into his concept of the "Periodic Table" in which Barium is just one element that can be found.
