Source-derived summary

Lucjusz Kupferwasser (born in 1888 in Lublin, Congress Poland) was a Polish-American social activist and one of the founders of the Józef Piłsudski Institute of America.

Early life

In 1905, he was expelled from school for his participation in the student strikes happening in the Russian Empire. In danger of being arrested, he immigrated to the United States in 1910, where he initially settled in Cleveland, Ohio. He was active in the Polish National Alliance and the Polish National Defense Committee and served as a financial secretary in the latter organization.

On the front

When the United States joined the Entente in World War I, Kupferwasser volunteered for the American Army, in which he served as an aviation mechanic. He was strongly poisoned by chemical weapons on the Western Front. Upon his return to the United States, he moved back to Cleveland. In 1935, he moved to Chicago. He was active in the Polish Maritime and Colonial League as well as the American Polonia Council.

World War II and aftermath

After the outbreak of World War II, Kupferwasser was one of the founders of the National Committee of Americans of Polish Extraction (KNAPP), of which he became one of directors in 1945.

The current lead gives the account dated anchors—1888, 1905, 1910, 1935—that can be checked directly. The linked authority record independently contributes the date 1888. The account is most persuasive where Lucjusz, Kupferwasser and Polish-American can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as polish-American activist. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 19, 2026. The linked authority identifier is Q15890664.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
