The origin and evolution of Lithium-Beryllium-Boron is a crossing point
between different astrophysical fields : optical and gamma spectroscopy, non
thermal nucleosynthesis, Big Bang and stellar nucleosynthesis and finally
galactic evolution. We describe the production and the evolution of
Lithium-Beryllium-Boron from Big Bang up to now through the interaction of the
Standard Galactic Cosmic Rays with the interstellar medium, supernova neutrino
spallation and a low energy component related to supernova explosions in
galactic superbubbles.Comment: 28 pages, 7 figures, to be published in a special memorial volume of
Physics Reports in honor of David Schram
