Allan Campbell noted the injustice of Stanford's attitude toward women scientists in a letter of recommendation for Esther Lederberg, written in 1971: "I think she is a definite asset to the University and merits promotion according to the normal customs of your department (i.e., that your Committee on Women's Promotions should recommend advancement on the same time schedule as a Committee of Men's Promotions would advance a male scientist)."
Allan Campbell fixo notar a inxusta actitude de Stanford cara ás mulleres científicas nunha carta de recomendación paira Esther Lederberg escrita en 1971: "penso que ela é moi valiosa para a Universidade e merece un ascenso de acordo aos costumes habituais do seu departamento (por exemplo, que o seu Comité de Promoción das Mulleres recoméndea da mesma maneira que un Comité de Promocións dos Homes faría ascender a un científico home)."
