Abstract
I will discuss the role of each of the contributors to the discovery of the Universe expansion, namely Edwin Hubble, Georges Lemaître and Vesto Slipher concentrating in particular on the pioneering role of the last (what is much less known). This discovery led to the no less important finding that our Universe had an origin. I will then shortly sketch a couple of new approaches to tame the cosmological constant and a hot issue concerning the value of the Hubble parameter.
