- In 1751, Joshua Humphreys was born in Haverford, Pennsylvania, and became the nation's most important naval architect in the post-Revolutionary era concerned with building and retrofitting military fleets. His most well-known ship is the
Constitution, which is known as "Old Ironsides" and is the oldest commissioned U.S. naval vessel still afloat. In 1803, Humphreys retired, and his son Samuel continued the business. This collection consists of volumes, including daybooks and financial records; correspondence; family papers; and legal documents.
