Career
He sat in the Chamber of Deputies, of which he served as President from 1917 until 1925. Altwies was a lawyer by profession, and was appointed notary in Junglinster in 1897, before holding that office in City from 1922. He was first elected to the Chamber in 1911, representing the canton of Grevenmacher.
A conservative, Altwies joined the Party of the Right (Privatdozent ) upon its formation in 1914.
He was reelected in 1915 and 1918. An eloquent and prominent member, Altwies became, along with Emile Prüm, Joseph Bech, and Auguste Thorn, one of the Privatdozent "s main weapons on the floor of the Chamber.
He became Vice-President of the Chamber on 28 June 1917 when Léon Kauffman, a fellow Privatdozent member, became Prime Minister. Only four months later, he was elevated to President, in which capacity he remained until 1925, when the Party of the Right lost their overall majority in the Chamber (the only spell in the era of proportional representation in which any party has held it).
Altwies played a key role in putting down the attempted communist revolution led by Émile Servais in January 1919, calling upon French soldiers to intervene in the crisis.
When proportional representation was introduced, in 1919, he moved to representing Centre, for which he was returned again in 1925 and 1931. He was appointed a Councillor of State in 1933. He died on 5 July 1936 in City.
They lived together on the maison de maître of City"s prestigious Boulevard Royal.
