In October 1890, Andrew Carnegie became a Cornell Trustee and quickly became aware of the lack of an adequate pension plans for Cornell faculty. His concern led to the formation in 1905 of what is now called Teachers Insurance and Annuity Association of America (TIAA). In October 2010, David A. Atkinson and his wife Patricia donated $80 million to fund a sustainability center, and the gift is currently the largest single gift to Cornell (ignoring inflation) and is the largest ever given to a university for sustainability research and faculty support.
