In addition to Dewey’s sexism, the ALA resolution to drop his name, which was ratified unanimously by the organization’s governing council, also cited his anti-Semitism and racism. At a private club he owned on Lake Placid, Dewey did not allow Jews or blacks to become members or visitors. A club pamphlet read: “No one shall be received as a member or guest, against whom there is physical, moral, social or race objection. … It is found impracticable to make exceptions to Jews or others excluded, even when of unusual personal qualifications.” When news of the pamphlet became public, also in 1906, Dewey was forced to resign from his state library position.
