Gustav Heinrich Johann Apollon Tammann (9 June [O.S. 28 May] 1861 – 17 December 1938) was a prominent chemist-physicist of Estonian and Baltic-German descent who made important contributions in the fields of glassy and solid solutions, heterogeneous equilibria, crystallization, and metallurgy.

Tamman was born in Yamburg (now Kingisepp, Leningrad Oblast). His father, Heinrich Tammann (1833–1864) was of Estonian peasant origin and his mother, Matilda Schünmann, was of German origin. Tamman graduated from University of Dorpat in chemistry. He came to Göttingen University in 1903 where he established the first Institute of Inorganic Chemistry in Germany. In 1908 he was appointed director of the Physico-Chemical Institute. His interests focused on the physics and physical chemistry of metals and alloys (metallurgy). In 1925 Tammann was awarded Liebig Medal. On 28 May 1936, Tammann was awarded the shield of nobility of the German Empire (Adlerschild des Deutschen Reiches), with dedication "The Doyen of German Metallurgy". Tammann died in Göttingen at age 77.
