Ludwig Flamm, who came from a family of watchmakers, studied physics at the University of Vienna.
In 1916 he was awarded the pro venia legendi at the Technische Universität Wien and in 1919 achieved a professorship.
From 1922 to 1956 Flamm was a full professor and board member for physics at the Technische Universität Wien.
Flamm was married to Elsa, the youngest daughter of Ludwig Boltzmann.
He was the first to describe solutions that lead to connections, now called wormholes, in the spacetime continuum.
