House History Timeline, 1900–1999


November 9

Representative Joseph Gurney Cannon of Illinois was elected Speaker for the first time. “Uncle Joe” Cannon became one of the House’s most powerful Speakers as a proponent of less legislative intrusion on growing American industry.


January 9

With the completion of the first House Office Building construction, Members drew numbers to occupy personal offices for the first time. As a result, five years later, the House approved new theater seating in its chamber to replace Members’ individual desks.


March 19

Nearly 200 Members of the House banded together to strip Speaker Joseph Cannon of his power to appoint Members to the influential Committee on Rules. Known as the Cannon Revolt, the action greatly curtailed the Speaker’s absolute control over the House Chamber and proceedings.


April 2

Representative Jeannette Rankin of Montana became the first woman Member.


May 21

After the Senate failed to pass the 19th Amendment in the prior Congress, the House again passed the measure which granted women the right to vote.

June 11

The House passed the Permanent Apportionment Act of 1929, setting the number of Representatives at 435. After each decennial census since 1930, seats have been apportioned among the states using the formula established in that act.


June 14

In an attempt to jumpstart the domestic economy, the House passed the Smoot-Hawley Tariff, raising duties once again to extremely high levels. The tariff backfired, severely inhibiting foreign trade and sending the American economy deeper into the Great Depression.

November 4

The Republicans won a narrow majority of House seats in the fall elections, but the deaths of 19 Members-elect before the opening of the 72nd Congress (1931–1933) allowed the Democrats to gain a majority after a series of special elections. Texas Representative John Nance Garner was elected Speaker of the House.


September 16

The House elected Representative Sam Rayburn of Texas Speaker for the first time. The longest-serving Speaker, Rayburn later was instrumental in expanding the Committee on Rules to dilute the power of racial conservatives opposed to social legislation.

May 18

The House unanimously passed the Servicemen’s Readjustment Act (GI Bill of Rights) which provided far reaching educational aid, employment assistance, medical care, and housing opportunities for returning World War II veterans. Edith Nourse Rogers of Massachusetts, a long time advocate for U.S. veterans, helped craft many of the bill’s provisions.


August 2

The House passed the first Legislative Reorganization Act, a sweeping set of reforms that limited the number of House Committees, increased office allowances, and required lobbyist to register.


August 25

Based on testimony by former Communist Party member Whittaker Chambers, the House Committee on Un-American Activities (HUAC), chaired by J. Parnell Thomas of New Jersey, grilled former State Department official Alger Hiss as part of an investigation into his alleged work as a Soviet spy. The Hiss–Chambers hearings dominated headlines and epitomized wide-ranging congressional anti-communist investigations during the early Cold War.
