Donald G. Brotzman, 82, a former Colorado Republican who represented Boulder in the U.S. House of Representatives and then became a lobbyist, died of cancer Sept. 15 at the Fountains at Washington House, a nursing home in Alexandria. He lived in Alexandria.

Rep. Brotzman served from 1963 to 1965 and again from 1967 to 1975. He was unsuccessful in his reelection bids in 1964 and 1974 -- years of Democratic landslide victories.

In the House, he was on the Ways and Means Committee.

In 1975, President Gerald R. Ford appointed him assistant secretary of the Army for manpower and reserve affairs. He served two years and later wrote that his job was making "the all-volunteer army work."

He later became president of the Rubber Manufacturers Association, a trade group; chairman of the Highway Users Federation Policy Committee and the Tire Industry Safety Council; and counsel to the Washington office of the Chicago law firm Hopkins, Sutter, Hamel & Park.

Donald Glenn Brotzman was born on a farm near Sterling, Colo. He served in the Army in the Pacific theater during World War II. He was a 1949 graduate of the University of Colorado schools of Business and Law. He had started his undergraduate work before the war on a football scholarship.

He was a lawyer in Boulder before beginning his political ascent, first in the state House of Representatives and then the state Senate. He made two unsuccessful runs for governor before President Dwight D. Eisenhower appointed him U.S. attorney for Colorado in 1959.

In 1963, when he first arrived in Washington, he told a reporter he was mystified by the astonishingly long job titles in government.

He pointed to one in particular: "assistant to the deputy special assistant to the assistant for space office, deputy director, research and engineering (tactical warfare programs) of the Defense Department's tripartite cooperation program, Subgroup M, military space research."

"His calling card would have to be printed in two volumes," Rep. Brotzman said.

He was a Mason and a member of Providence-Fort Washington United Methodist Church in Fort Washington.

His wife of 51 years, Louise Reed Brotzman, died in 1995.

Survivors include his wife, Gwendolyn Davis Brotzman of Alexandria, whom he married in 1996; two children from his first marriage, Kathleen "Kathy" Caldwell of Longmont, Colo., and Donald G. "Chip" Brotzman Jr. of Carbondale, Colo.; a stepson, Robert Higgins of Philippi, W.Va.; a brother; and six grandchildren.
