History
The United States District Court for the District of Pennsylvania was one of the original 13 courts established by the Judiciary Act of 1789,, on September 24, 1789. It was subdivided on April 20, 1818, by, into the Eastern and Western Districts to be headquartered in Philadelphia and Pittsburgh, respectively. The court began its first session on December 7, 1818 at the Old County Courthouse in Pittsburgh. Portions of these districts were subsequently subdivided into the Middle District on March 2, 1901, by 31 Stat. 880. At the time of its initial subdivision, presiding judge Richard Peters Jr. was reassigned to only the Eastern District. This made it possible for President James Monroe to appoint Jonathan Hoge Walker as the first judge of the Western District of Pennsylvania.

The Erie courthouse and division was split from Pittsburgh for initial actions in January 1867, with the Johnstown courthouse and division being split from Pittsburgh for initial actions in 1989.
