text: On July 1, 1992, the National Foundation for History of Chemistry changed its name to the Chemical Heritage Foundation, in recognition of the international nature of chemical history. By 1994, the organization was searching for a permanent home for the Beckman Center and Othmer Library. One candidate was the First National Bank building at 315 Chestnut Street, an 1866 masonry-and-brick structure with a two-story Palazzo facade. The institution bought the bank building and nearby property in 1995, in part with a matching grant from Donald Othmer.  Soon afterward, its endowment was expanded by a bequest from Othmer's estate.  The Chemical Heritage Foundation moved to 315 Chestnut Street on February 1, 1996.  The buildings were renovated by Richard Conway Meyer over the next few years. Phase 1, providing temporary office space and book storage, was completed in 1998.  Phase 2, a move to more permanent facilities, was completed in 2000. Phase 3, construction of the adjoining Ullyot conference space for meetings and events, began soon after.
