Alexander Porfiryevich Borodin was a Romantic composer and chemist of Georgian-Russian extraction. He was one of the prominent 19th-century composers known as "The Five", a group dedicated to producing a "uniquely Russian" kind of classical music. Borodin is known best for his symphonies, his two string quartets, the symphonic poem In the Steppes of Central Asia and his opera Prince Igor.

Charles Adolphe Wurtz was an Alsatian French chemist. He is best remembered for his decades-long advocacy for the atomic theory and for ideas about the structures of chemical compounds, against the skeptical opinions of chemists such as Marcellin Berthelot and Henri Étienne Sainte-Claire Deville. He is well known by organic chemists for the Wurtz reaction, to form carbon-carbon bonds by reacting alkyl halides with sodium, and for his discoveries of ethylamine, ethylene glycol, and the aldol reaction. Wurtz was also an influential writer and educator.
