Bogdan Feliks Raczkowski (12 March 1888 – 4 October 1939) was an influential engineer, builder and urbanist in Bydgoszcz from the 1920s till the outbreak of World War II.

As a result of the Russian October Revolution the same year, the couple fled Russia by boat across the Black Sea and got back home to Poznań after a journey through Romania, Hungary and Czechoslovakia.

After a dispute at the municipal council, Bogdan Raczkowski was dismissed these positions in April 1934: he then became an appraiser at the Bydgoszcz branch of Bank Gospodarstwa Krajowego.

On her side, Maria was active in Bydgoszcz branch of the Polish White Cross, the social movement created in February 1918 by Helena Paderewska, second wife of Ignacy Jan Paderewski.

[4] Fleeing the Nazi invasion, the Raczkowski's left Bydgoszcz and moved to Marie's family estate in Kutno in September for one month.

When they came back, their house at 1, Asnyka street was occupied by a German officer: hence they moved to live at a cousin's flat, Stefan Jeżowski, on Weyssenhoff Square.

Bogdan Raczkowski also painted pictures: landscapes of places he visited (Zakopane, Ciechocinek, Hel, Orłowo, Kharkiv, Rostov, Sevastopol, Capri, Rome).

[7] At the same time, Raczkowski prepared an expansion project to give an area further north (Skrzetusko) an homogeneous character (sector defined by streets Płocka, Chodkiewicza, Sułkowskiego and Kozietulskiego).

Bogdan Raczkowski devised a grand urbanization project for the city, intending to support private construction initiatives and identifying specific areas to be developed.

In addition to Sielanka and Skrzetusko districts, he focused his attention to streets Czarna Droga, Dwernickiego, Libelta, Niemcewicza and Piotrowskiego.

At a time when neoclassicism was declining, technical and industrial progress opened up building potentials, with state-of-the-art materials (steel and glass) and innovative methods.

In addition to the following realizations, Raczkowski also conceived habitations at Babia Wieś (1926-1927), at 22-38 Żwirki i Wigury street (1930) and prepared in the early 1920s a project -never carried out- for the basilica of St. Vincent de Paul in Bydgoszcz.

The stained glasses in the chancel dating back to the inception of the church (1924) have been funded by Bydgoszcz mayor Bernard Śliwiński and city councillor Arthur Franke.

The previous and outdated house was put into service on 9 December 1885 as an element of one of the first hospital ensemble in Bydgoszcz funded by a donation of Ludwika Giese-Rafalska, the owner of an estate in the south-east of the city.

Located on the south-west side of the square, its shape sticks to the gentle arc of the bordering avenue (Ossoliński Alley in Bydgoszcz).

It was designed by Raczkowski with engineer Kazimierz Michał Orlicz and built in 1 year, a record at a time of economic crisis,[22] to host Ewaryst Estkowski Public School.
