From Pittsburgh Streets

Neighborhood South Side Slopes
Origin of name Tadeusz Kościuszko
Kosciusko Alley (until 1914)
Origin of name Tadeusz Kościuszko

This alley appears as Kosciusko Alley in the 1890 Hopkins atlas;[1] it became Kosciusko Way in 1914 when a city ordinance changed all alleys to ways.[2] It is named for Tadeusz Kościuszko (1746–1817),[3][4] a Polish military engineer who served as a colonel in the Continental Army during the American Revolutionary War and later became a military leader in Poland.

This alley used to be the road which led into the estate of Oliver H. Ormsby, for whom Mount Oliver is named; his sisters gave their names to Jane Street, Sarah Street, Sidney Street, Mary Street, and Josephine Street.[3] (See Ormsby Street for more about the Ormsby family.) The Ormsby property was later purchased by Joseph Makowiski and John Warzynski, two of the first Polish millworkers to live in that part of the South Side, and this is why Kosciusko Way has a Polish name.[3]
