Jan Oudegeest

Jan Oudegeest (5 August 1870 – 10 October 1950) was a Dutch trade unionist and politician.

When the Nederlands Verbond van Vakverenigingen was founded in 1906, Oudegeest became its first secretary, and in 1909 he took over as its president, serving until 1919.

In this role, Oudegeest was highly critical of the Christian trade unions, believing them to be pro-capitalist.

In 1919, he was a prominent founder of the International Federation of Trade Unions, and served as joint secretary until 1927.

That year, he stood down, becoming chair of the Social Democratic Workers' Party, and in 1928 he was also elected to the Senate.
