Her eight children with Jan were well-educated: Franciszek was the chief secretary of the appellate prosecutor's office in Thorn and mayor of Nowe Miasto Lubawskie; Tadeusz became a medical doctor; and Bronisław became a politician, lawyer and activist.

After graduating from primary school, six grades of pro-gymnasium in Löbau and legal studies in Berlin, Kurzętkowski moved to Chełmża in 1907.

Polish and German relations continued to break down, causing an uprising in 1919 that saw the shelling of Chełmża following the installation of Grenzschutz units in the city.

After the Polish authorities took over Chełmża on 21 January 1920, Kurzętkowski was appointed acting mayor of the city until the following election, which took place on 5 November 1921.

He hired as many educated officials of Polish origin as possible in the Chełmża city hall and launched an intensive construction campaign.

During Kurzętkowski's term of office, the street network was expanded, electricity lines were installed and an archery range and city stadium were built.

Shortly before Poland regained independence, Kurzętkowski resigned from his position as a Prussian official without the right to a pension and devoted himself to working for the Supreme People's Council in Poznań.

In October 1927, he was accused by the government of financial irregularities in the leases[citation needed] of the Archidiakonka Lake,[4] the fruit alley and market fuels, and in purchases including business trips, renovations of tenement houses, a lifeboat and a police horse.

In the early 1930s, Kurzętkowski became involved with the Sanation movement, as well as with the Pomeranian Insurance Association in Toruń as a member of the governing council.

During his short term, he established the Mogilno agricultural school and served as the first president of the Society of Allotment Gardens.

[6] During a meeting at a school on 15 February 1939, Kurzętkowski suddenly fainted and lost consciousness due to a heart attack.

During World War II, the Nazis occupied his villa[citation needed] at today's Sikorskiego Street 45[7] and took possession of the furniture and belongings.
