text: On December 1, 2015, the Chemical Heritage Foundation merged with the Life Sciences Foundation, also founded by Arnold Thackray.  Recognizing that the joint organization's interests extended beyond the field of chemistry, the organization began a two-year renaming process, whose outcome required the agreement of its founding partners, the American Chemical Society and the American Institute of Chemical Engineers.  On February 1, 2018, the organization was renamed the Science History Institute, to reflect its wider range of historical interests, extending from the chemical sciences and engineering to the life sciences and biotechnology.
