Lars brink colleague, friend and collaborator

The Landau-Nordita conference that was held in Moscow in 1981 was the first place where I met Lars. This “marvelous meeting”, as Lars quoted in one of his reminiscence papers, was organized by Alan Luther. It was an event that generated a long-lasting friendship of scientists from East and West, provided a background for the future collaborations and, in particular, my own collaboration with Lars on a supersymmetric high-spin extension of the Poincaré group.
