Life 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…Citește mai mult
