Kenneth Robinson (1980, vii) attributes the invention of equal temperament to Zhu Zaiyu and provides textual quotations as evidence (Robinson and Needham 1962, 221). Fritz A. Kuttner is critical of this theory (Kuttner 1975, 163) and proposes that neither Zhu Zaiyu nor Simon Stevin (Stevin (1884)) achieved equal temperament, and that neither of the two should be treated as inventors (Kuttner 1975, 200).
