Géza Gusztáv Zemplén, Ph.D. (26 October 1883 – 24 July 1956) was a notable Hungarian chemist, organic chemist, professor, and chemistry author. He was a recipient of the Kossuth Prize, a member of the Hungarian Academy of Sciences, and was the brother of Professor Győző Zemplén. His major field of research was structural chemistry and biochemistry including the synthesis of naturally occurring flavonoid-glycosides (isolated from plants).
Géza Zemplén was born in Trencsén, the son of János Zemplén and Janka Vittlin, both Roman Catholics. After having completed his secondary education in Fiume, he enrolled in the Eötvös College Budapest in 1900. During his studies he produced two prize-winning works in the sciences. In 1904 he obtained a Ph.D. (doctor rerum naturalium). After having completed his probationary year of teaching, he became a certificated teacher. He then joined the faculty of the College of Mining and Forestry in Selmecbánya in 1905. One year later he was promoted to the post of adjunct professor. He married Margit Heinrich Johanna Friderika (the Roman Catholic daughter of János Heinrich and Emilia Turnovszky) in 1907 in Budapest. However, they were divorced in 1920.
In order to gain further expertise in organic chemistry Zemplén left for Berlin where he worked for 2.5 years for the renowned professor Emil Fischer, first as an assistant and later (on Fischer's invitation) as a colleague in his private laboratory. On the invitation of Emil Abderhalden, an eminent biochemist, Zemplén participated in the writing of Biochemisches Hand-lexikon and also Handbuch der biochemischen Arbeitsmethoden. In 1910 Zemplén returned to his job in Selmecbánya where he was presented the Hungarian Journal of Chemistry Award as well as the Hungarian National Society of Forestry Award. In 1912 he was qualified by the University of Budapest as doctor habil, and in 1913 he was appointed the Head of the newly created Department of Organic Chemistry of the Palatine Joseph Technical University. Beginning in 19l4, he acted as the councilor of the Budapest's Chinoin Pharmaceutical Factory.
