# From spin models to lattice QCD -- the scientific legacy of Peter Hasenfratz

## TL;DR

This paper reflects on Peter Hasenfratz's influential contributions to lattice QCD and the lattice community, highlighting three key ideas that continue to impact the field today.

## Contribution

It details three specific ideas introduced by Hasenfratz that have shaped current research in lattice QCD and community organization.

## Key findings

- Initiated the first lattice conference at CERN in 1982
- Contributed key ideas that influence current lattice QCD research
- Fostered community development in lattice field theory

## Abstract

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.
