An engineer and architect who was born 25th December 1895 in Pabianice. He went to a trade school there and received his secondary education. He was in the scouts which shaped his patriotism. In 1929, he received his diploma at the Faculty of Architecture at the Warsaw University of Technology. He came to Gdynia as a representative for an investor (Stanisław Szwalbe, the president of the Communal Building Company in Warsaw) to build a workers’ housing estate in the Grabówek district. He established a housing cooperative called Economic Housing Construction Cooperative together with an engineer and architect Włodzimierz Prochaski and an engineer Mieczysław Michalski.
Together with Prochaski, he designed two stretches of terraced houses in Marszałka Ferdynanda Focha Street. The architect moved into the house no. 20. His two daughters were born there. Until 1939, he was the head of the Warsaw Communal Building Company in Gdynia.
Maciejewski was called up in August 1939. He took part in September Campaign, fought in Hel and spent the rest of the war as a prisoner in the Oflag II C Woldenberg camp. After the war, he spent a short time in his family town, Pabianice where he was recovering. Then, he returned to Gdynia and settled there for good. He opened an architectural design office. After 1945, he became involved in the reconstruction and growth of Gdynia. The mayor entrusted him with the reconstruction of the city’s war-damaged schools.
Maciejewski was motivated by the idea of providing the workers’ families with humanitarian housing conditions. He worked for the Gdynia Housing Cooperative in today’s Wzgórze Św. Maksymiliana district. He was the technical director of the Workers’ Housing Estate Construction Management. In 1955, he transferred to the Provincial Office for Rural Construction Projects in Gdańsk and worked there until 1964 when he retired. On 5th September 1962, he became the president of Gdynia branch of the Polish Association of Astronomy Lovers (and since 1968 of the merged Gdańsk and Gdynia branches). He chose building an astronomical observatory in Kamienna Góra as his goal. In order to archive it, he prepared preliminary sketches and a design, however due to a lack of grants or funds, it was never completed.
Since 1925, he was a member of the Planning Committee of the Town Council (he struggled for a logical and harmonious preservation of Gdynia’s architecture and expansion of the city’s development). He withdrew from it in 1966 due to his health condition. Maciejewski was a member of the Association for the Construction of Housing Estates and the Gdynia branch of Association of Polish Architects as well as its Pomeranian branch. He also worked as an investment appraiser for Bank Gospodarstwa Krajowego in 10 Lutego Street in Gdynia. In 1971, he was awarded a Silver Honorary Decoration of the Polish Association of Astronomy Lovers. Though he died from a serious disease on 8th May 1972 in Gdynia, he was buried in Pabianice.
