Piotr Triebler was born on 22 November 1898 in Ligota Bialska, Opole region, part of then Prussian Province of Silesia.

Most of his works were created in his workshop at 94 Dworcowa street in Bydgoszcz, ran together with Teodor Gajewski - a sculptor with similar artistic penchants.

[1] As a matter of fact, Triebler at the time designed a number of commemorative plaques in Bydgoszcz, such as The liberation of the city of Bydgoszcz-1920 (1930) and The kings Stefan Batory and Jan III Sobieski (1933, together with Teodor Gajewski).

After the liberation, he joined the effort of many other artists who devoted their work to bring life out of the ruins of the devastated area around Bydgoszcz.

As he did before the conflict, Triebler created sculpted monuments as well as chamber works: portraits, reliefs, medallions, but he also dealt with drawings and paintings.

He realized several plaques: The artist undertook at the time the challenge to restore a city famous monument, damaged by war, Ferdinand Lepcke's Archer (Polish: Łuczniczka),[4] as well as recraft the statue of Mary destroyed by the Nazis in 1939, which used to stand outside the Church of the Holy Trinity.

He died from long heart condition on 31 March 1952 in Bydgoszcz, where he was buried at the Catholic cemetery of the Holy Trinity at Lotników Street.

[5] At the end of March 1960, Tadeusz Rączka came to Bydgoszcz and appeared a first time at Cecylia's address, introducing himself as a conservator of monuments, who wanted to place a large order for tombstones.

The criminal went back to the Trieblers' house on 30 March, where Gabriela (18), a promising athlete and Paweł (14), dreaming to follow his father's footsteps and become a sculptor, were staying.

Surprised in his robbery, Rączka killed both children and fled with a meagre loot (a fur coat, a camera and two watches).

Rapidly, a large-scale search began, with the police blocking exit roads from Bydgoszcz and disseminating the description of the murderer.
