John M. Wenneis, PhD

Jack Wenneis may have been the first Honorary Member of The Society of Flavor Chemists.

He worked originally for Monsanto Chemical Co, and subsequently had his own company which was bought by Herman Kohl of Norda, where he worked for the rest of his career.

Monsanto was one of the first US Chemical companies to experiment with the manufacture of aroma chemicals, in the early 1900’s. They made the first Vanillin in the US – from clove oil, and also produced Salicylic acid, Methyl Salicylate, Coumarin and other aromatics.  Dr. Wenneis was one of the first in the US to synthesize Diacetyl, and he one of the first to commercialize Hydroxy Citronellol.

Al Saldarini, an SFC Emeritus member, recognizes Jack Wenneis as his mentor and states that Jack was one of the most astute and ethical chemists in the country.
