Portsmouth-born John Langdon was elected New Hampshire's first United States senator. Langdon, a delegate to the Constitutional Convention and a signer, was serving as president (governor) of the state at the time of his election.
Paine Wingate, born in Amesbury, Massachusetts, but later of Stratham, New Hampshire, was elected New Hampshire's second U.S. senator.
The Senate convened for the first time at Federal Hall in New York City. New Hampshire senators John Langdon and Paine Wingate both took their seats, but because only eight senators were present, there were not enough to constitute a quorum. The body was forced to adjourn each day until April 6, when it achieved its first quorum of 12 members, out of the eligible 22.
The Senate drew lots to determine the three classes of senators. Senator John Langdon was assigned the Class 3 seat (with a six-year term to expire in 1795) while Senator Paine Wingate was assigned the Class 2 seat (with a four-year term to expire in 1793).
Vice President John Adams administered the oath to support the Constitution to all senators present, including John Langdon and Paine Wingate. The statute regulating the taking of an oath, mandated by Article VI of the Constitution, was enacted on June 1, 1789.

Williams took his Senate seat on December 12, but in July 1854, questions were raised as to whether his appointment had expired when the state legislature met in June of that year, or only when it elected a successor. After a committee investigation, the Senate adopted a resolution in August 1854 declaring that "the right of representation under the appointment" had expired. The vacant seat was filled on July 30, 1855, with the election of former senator John P. Hale.
A professor of mathematics, astronomy, and meteorology at Dartmouth College, James Willis Patterson of Hanover began his Senate service.
