George Clymer was a successful merchant, well-known politician, and a generous philanthropist, but is today most famous for being a signer of the Declaration of Independence. As a proponent of independence, he joined various local political committees including six of the seven Philadelphia resistance committees. From there, he entered the national political arena and in 1776 was elected to the Second Continental Congress where he signed the Declaration of Independence. The George Clymer Collection is a small one and not reflective of his varied pursuits. There are twenty-seven documents, most of which are not signed by Clymer; those that are signed by Clymer are dated between May 3, 1800 and January 22, 1813. The items represent not Clymer's political activities but his ordinary legal and real estate transactions.
