The downtown Post Office on Monday will be named the Barber B. Conable Jr. Post Office.
The dedication at 11:30 a.m. will honor the Alexander resident who served for 20 years in Congress, and five years as president of the World Bank. Conable died a year ago.
At the ceremony will be U.S. Sen. Charles E. Schumer, D-N.Y., and Rep. Thomas M. Reynolds, R-Clarence, who sponsored the legislation to have the post office named for Conable.
The area's first post office opened in 1802 in a general store operated by James Brisbane. The present building was completed in 1919.
