Members Who Have Served in the
U.S. Congress 30 Years or More
Summary
This report identifies those 234 Members of Congress whose service in the
House or Senate, or both, has been 30 years or more. The information provided is
current through July 7, 2007.
To place this information in perspective, it should be noted that some 11,814
individuals have served in Congress since 1789. Excluding Delegates and Resident
Commissioners, this includes 9,919 persons who have served only in the House,
1,250 persons who have served only in the Senate, and 645 who have served in both
houses.
Of the names listed here, 137 have spent all of their congressional careers in the
House; 27 have spent all of their careers in the Senate; and 70 have had combined
service in the House and Senate to achieve 30 or more years of service. Three
women are included in the listing. Seventeen incumbent Senators and 17 incumbent
Representatives have served 30 years or longer.
This report will be updated as events warrant.

Members Who Have Served in the
U.S. Congress 30 Years or More
This report contains the names of all Members of the United States Congress
who have served 30 or more years, as of January 3, 2006. The names are listed in
order of length of congressional service. Party affiliation, state(s) represented,
service in the House or Senate, or both, and total length of congressional service are
provided for each Member.
As of July 7, 2007, a total of 234 individuals have served 30 or more years in
Congress. To place this figure in perspective, it should be noted that 11,814
individuals have served in Congress since 1789.1 It is of further interest to note that
only nine of the 234 individuals with 30 or more years of service served during the
18th and 19th centuries. The remaining 225 served entirely during the 20th century,
partially in the 19th century and partially in the 20th century, or partially in the 20th
century and partially in the 21st century. Seventeen incumbent Senators and 17
incumbent Representatives have served 30 years or longer. Their names are listed
in boldface type. Three women are included in the list. All served in the 20th century,
and their names are listed in italics.
In compiling the list, leap year days were calculated separately and added to a
Member’s years, months, and days of service. In addition, for Members who served
part of any year, the figure of 30 days was used to calculate the number of days in a
month when converting days into months. For example, if a Member served 30
years, eight months, and 36 days, 30 of the 36 days were used to constitute a month
so that the end result for this hypothetical Member would be 30 years, nine months,
and six days.
The sources for this compilation include a similar list appearing in “Service
Time of Congressmen,”Congressional Record, vol. 113, March 9, 1967, pp. 6191-
6193, which contained numerous inaccuracies, the Biographical Directory of the
American Congress, 1774-2005, and various editions of the Congressional Directory
(Washington: GPO).
1 This figure excludes Delegates and Resident Commissioners. It includes 9,919 persons
who have served only in the House, 1,250 persons who have served only in the Senate, and
645 who have served in both houses of Congress.
