Born: June 17, 1903 in Wiesbaden
Died: December 16, 1990 in Weilrod

The son of a social-democratic woodworker and an ironer, he worked as a casual laborer and temporary worker for ten years after leaving elementary school, but gained further qualifications by attending a technical college for civil engineering. In 1927, he was given a permanent position as a surveyor's assistant at the Wiesbaden city surveying office.

Having already joined the USPD, the Free Socialist Youth and the tourist association "Die Naturfreunde" in 1919, he also became a member of the KPD in 1927. In the same year, he switched from the Building Trades Union to the Municipal and State Workers' Association and became a member of the works council. He soon took over the leadership of the Communist Youth Association and later the Revolutionary Trade Union Opposition in the Wiesbaden sub-district. In 1932, he organized an anti-fascist committee in the municipal workplaces. The following year, the city councillor played a leading role in the early communist resistance activities against the "Third Reich".

Temporarily imprisoned in Wiesbaden police prison in March 1933, he went underground and was arrested again in May. He was imprisoned until the end of 1933, first again in the local police prison, then in the Freiendiez central prison and finally in the Esterwegen concentration camp. During those years, the family of five had to get by on a meagre welfare allowance, although this was topped up a little by donations from the illegal Red Aid organization. Despite police surveillance, Krüger resumed his resistance work in mid-1934. In the summer of 1935, he was arrested again and sent to Esterwegen concentration camp via four prisons. From the following year, he was harassed in Sachsenhausen concentration camp. In the fall of 1938, he was released from prison and returned to his hometown, but had to report to the Gestapo every day from then on. He was assigned a job as an excavator at the construction company Jakob Wiederspahn KG. He later worked there as a civil engineering technician and finally as a construction foreman until the end of the war.

In 1945, he was involved in the reorganization of the trade unions at company level, co-founded the Democratic Unity Trade Union Wiesbaden and was also involved in the anti-Nazi Reconstruction Committee Wiesbaden and, until the following year, in the local unity committee of the SPD and KPD and also in the Wiesbaden Citizens' Council as the "representative of the anti-national socialist forces" in the city. In 1946, he became Managing Secretary of the Public Administration and Works Union, Wiesbaden district, which later became the ÖTV. In the same year, he worked in the advisory state committee, then in the constitutional advisory state assembly of Greater Hesse and was elected to the first Hessian state parliament for the KPD. He had also been a member of his party's state executive committee since 1946. In 1947, he was one of the co-founders of the Association of Persecutees of the Nazi Regime. From 1948 to 1952, he was a city councillor and parliamentary group leader of the Wiesbaden KPD. In 1952, he was transferred to Frankfurt am Main and took over the legal department of the ÖTV there. From 1959, he served as its 2nd chairman and deputy managing director.

In 1968, Krüger retired from professional life and joined the newly founded DKP. He also served in numerous honorary positions, for example as an associate judge at the labor court in Wiesbaden, as a labor judge, state labor judge and judge at the administrative court, all in Frankfurt. Paul Krüger's estate can be found in the Wiesbaden City Archives.
