Historical And Foundational Chemists (Pre-1900)

was a Scottish physicist and chemist, known for his discoveries of magnesium, latent heat, specific heat, and carbon dioxide

known for his discoveries of the chemical elements gallium, samarium and dysprosium

His most famous paper, outlining his law on thermochemistry, was published there in 1840

He acquired international fame by determining the atomic weights of the elements more accurately than had ever been done before

was a French physicist and chemist who discovered the element thallium independently from William Crookes in 1862

He is famous for the Cannizzaro reaction and for his influential role in the atomic-weight deliberations of the Karlsruhe Congress in 1860.

He is credited with discovering the element thallium, announced in 1861, with the help of spectroscopy.

He is particularly noted for early work on vanadium, photochemical studies

He was one of the pioneers in developing the earliest versions of the periodic table of the chemical elements

In 1826 he discovered in seawater a substance which he recognized as a previously unknown element and named it bromine

Chemical analysis related to the process of purifying platinum led Wollaston to discover the elements palladium (symbol Pd) in 1802 and rhodium (symbol Rh) in 1804.

Berthollet was one of the first chemists to recognize the characteristics of a reverse reaction, and hence, chemical equilibrium.

He was promoted to full professor of medicine and professor of chemistry, botany, and mineralogy in 1778.
