A different kind of Nierenstein reaction. The Chemical Society's mistreatment of Maximilian Nierenstein.

Between 1920 and 1922, the University of Bristol biochemist, Maximilian Nierenstein, published four papers in a series exploring the structure of catechin in the Journal of the Chemical Society. The Society then abruptly refused to accept any more of his papers on catechin, or any other subject. It provided him with no reasons for the embargo until 1925. It then transpired that Nierenstein was boycotted because it was deemed that he had not responded adequately to criticisms of his work made by his rival in catechin research, the German natural products chemist, Karl Freudenberg. It was not until 1929 that, as a result of a petition by a group of his former Bristol pupils and friends, that Nierenstein was again permitted to publish in the Society's journal. The paper explores the Chemical Society's treatment of Nierenstein in detail, sheds new light on his career and his reaction to the Society's unprecedented boycott, examines some of the structural chemistry involved in the disputes, and discusses whether Nierenstein's research deserves the label of 'bad science'.
