Alfred E. Treibs (1899–1983) was a German organic chemist who is credited with founding the area oforganic geochemistry. He received his PhD underHans Fischer at theTechnical University of Munich. Fischer had received theNobel Prize in Chemistry for elucidating the structures ofporphyrins.
In the 1930s Treibs discovered metalloporphyrins in petroleum.[1] These porphyrins resemblechlorophylls. This discovery helped confirm the biological origin of petroleum, which was previously controversial.[2]
