This is a transcript of my conference talk in remembrance of Peter Hasenfratz who deceased earlier in 2016. One of Peter’s many important contributions to the lattice community has been the initiation of the first lattice conference at CERN in 1982. From among his many important ideas, which Peter contributed to our field, I choose to discuss three in some detail and show how they are influencing the subject today.
