He was one of Luxembourg's six Members of the European Parliament from 1979 until 1981.

Hamilius ran at the 1952 Summer Olympics, in Helsinki, in the 400 metres and 4 × 400 metres relay, in an athletics deputation best known for the inclusion of Luxembourg's only gold medalist, Josy Barthel. He is the son of Émile Hamilius (1897–1971), himself a former DP politician and Mayor of Luxembourg City (1946–1963), as well as having competed at the Summer Olympics (in 1920), like his son.
