Guarantee of financial support for student James Savage, signed by William Tudor and John Cooper, 1799 July 25

This legal agreement, a guarantee of financial support for entering student James Savage (A.B. 1803), was signed on July 25, 1799 by his two guarantors, William Tudor and John Cooper. The document was also signed by two witnesses, William Tudor's sons John Henry Tudor and Frederic Tudor. The agreement specifies that, in the event of Savage's failure to settle all financial obligations to the President and Fellows of Harvard College during the course of his studies, the two guarantors would be responsible for a payment of two hundred ounces of silver. It seems that the Tudors and Cooper were relatives of Savage, thus explaining their desire to assure his entry to Harvard by entering into this financial obligation.
