Liberal League (Luxembourg) politicians

Jean-Baptiste Auguste Liesch (18 August 1874 – 13 March 1949) was a Luxembourgish liberal politician, writer, and civil servant.
He held the positions of Director-General for Justice and Director-General for Public Works in the government of Émile Reuter from 28 September 1918 to 15 April 1921. A member of the Liberal League, Liesch resigned from the government along with Michel Welter in 1921 in order to hold to account the majority Party of the Right.After his departure from the government, he served as the Inspector-General for Customs and Assizes until 1939. On 23 January 1937, he was appointed to the Council of State of Luxembourg, in which he sat until 16 November 1945 (although only nominally for most of that period, due to the German occupation of Luxembourg in World War II).

Gaston Diderich (18 June 1884 – 29 April 1946) was a Luxembourgish politician and jurist. He was the Mayor of Luxembourg City from 1921 until his death in 1946, making his the longest uninterrupted tenure in the city's history. In addition, Diderich was a member of the Chamber of Deputies from 1918 until 1940, and again from 1945 until his death the following year.
Diderich started political life in the Liberal League, of which he was on the progressive wing. After the German occupation during the First World War, the Liberal League found itself in opposition for the first time and suffered ideological divisions. Diderich, being Mayor of Luxembourg City, took the role of leading the left-wing of the party, opposed to the leadership of the classical liberal Robert Brasseur, who had founded the party in 1904. The left-wing eventually triumphed, but only at the price of collapsing the party. The main party of the party, predominantly the left-wing, reformed as the Radical Socialist Party,. under Diderich's leadership.
