J. Edgar Chenoweth, 88, a Republican who represented southern Colorado in the House of Representatives for 11 terms before his defeat for reelection in 1964, died Jan. 2 at a hospital here. The cause of death was not reported.

Mr. Chenoweth served in the House from 1941 to 1949, and again from 1951 to 1965. In addition to his 1964 defeat, he had lost a reelection race in 1948. After leaving Congress, he had practiced law in his native Trinidad.

During his years in the House, he was credited with helping establish eight military installations in Colorado, including the Air Force Academy, the Air Defense Command and the Fort Carson Army post. His committee assignments included service on the old Public Lands and the Ways and Means committees. He also chaired a special subcommittee investigating State Department expenditures.

In 1984, he received the Army's Patriotic Service Award for his role, as a freshman congressman, in persuading the Army to make Camp Carson a permanent post.

Mr. Chenoweth attended the University of Colorado and was admitted to the Colorado bar in 1925. He was a prosecuting attorney, then served as a county judge from 1933 to 1941, before entering Congress. He was chairman of the Colorado Republican State Central Committee from 1937 to 1940, and was a past secretary of the Republican Congressional Committee.
