October 8-10 – The Great Chicago Fire destroys much of Chicago; the Academy’s building and holdings are decimated, including materials housed in a special “fire-proof” vault.

Ayer resigns from the Board and turns to Marshall Field for the funds to build a new museum with Field’s name, ultimately becoming the Field Museum of Natural History.
October 31 – The Academy’s new building is dedicated and opens in Lincoln Park. The institution’s name, “Chicago Academy of Sciences,” was engraved on the front arch accompanied by the dedication of the building, “Matthew Laflin Memorial.” This building was referred to internally as the “Laflin Building.” The building was originally intended to be the north wing of a larger museum building with additions to be constructed in the future.
