Dr. Bryant Miner Wedge, 66, a psychiatrist and an authority on the peaceful resolution of conflict, died of a stroke Sept. 4 at the Washington Hospital Center. He lived in Washington.

Dr. Wedge played a major role in the establishment of the U.S. Institute of Peace, a nonprofit corporation funded by Congress. The institute, which opened in 1986, was created to help find ways to settle disputes between nations without violence.

In 1976, Dr. Wedge founded the National Peace Academy Campaign, a citizens organization that called for the creation of a national agency devoted to resolving conflicts peacefully. In 1979, he helped organize and became the director of the Center for Conflict Analysis and Resolution at George Mason University, which now offers a master's degree in conflict management.

Dr. Wedge also had been an adviser to the U.S. government. For the Central Intelligence Agency, he developed psychiatric profiles of various world leaders, including former Soviet premier Nikita S. Khrushchev.

He also maintained a private practice in psychiatry.

Dr. Wedge said that his interest in conflict resolution took form in 1959 when he was an Eisenhower Exchange Fellow to Europe, Africa and the Soviet Union. In the course of his travels, he attended an embassy party where officials of a Soviet-American university exchange program were screaming at each other.

"They were accusing each other of bad faith and sabotage," Dr. Wedge recalled in a 1984 interview in The Washington Post, "when it was just a bloody misunderstanding."

Dr. Wedge said he helped settle the dispute and realized "we like to think that those in high places know what they're doing and the world is safe. But from this close encounter I wasn't so sure."

Thus began his career of trying to persuade the world to use words instead of weapons to settle its differences.

A native of Coldwater, Mich., Dr. Wedge graduated from Kalamazoo College and received his medical degree from the University of Michigan. He served in the Army from 1952 to 1954 as assistant chief of psychiatric services at the Valley Forge Army Hospital in Pennsylvania. From 1954 to 1960 he taught at the Yale medical school. He then moved to Washington.

From 1973 to 1976, he was a medical adviser with the Social Security Administration. He served on the D.C. Mental Health Commission from 1976 to 1984 and was director of the South Community Mental Health Center from 1985 to 1987.

He was a member of the D.C. Psychiatric Society and the Group for the Advancement of Psychiatry.

His marriages to Dorothy Wedge, the former Vivian Rohrl, and the former Maggie Daugherty ended in divorce.

Survivors include two children by his first marriage, Karen Puckett of Arlington and Dan Wedge of Sussex, N.M.; one brother, Tom Wedge of Santa Clara, Calif., and four grandchildren.
