Lewis Norman Mander, AC, FAA, FRS (8 September 1939 – 8 February 2020) was a New Zealand-born Australian organic chemist.
He has widely explored the synthesis and chemistry of the gibberellin class of diterpenes over a 20-year period at the Australian National University (ANU).
He was a distinguished Alumnus Professor at the University of Auckland in 1992 and an Eminent Scientist of RIKEN at Wako, in Saitama Prefecture, Japan from 1995 to 1996.
Professor Sir Alan R. Battersby said that Mander's “...synthesis of gibberellic acid was a brilliant landmark achievement.
[9] Amongst his many scholarly activities, Mander contributed a chapter on 'Stereoselective Synthesis' to the classic text 'Stereochemistry of Organic Compounds' by Professors Ernest L. Eliel and Samuel H. Wilen.
