SIGSOFT50

ACM SIGSOFT 50th Anniversary Celebration

A story of people, institutions, memory, and renewal

At FSE 2026 in Montreal, the software engineering community gathered to mark fifty years of SIGSOFT and to ask what the next fifty should make possible.

The celebration brought together reflections on SIGSOFT's role in the field, recognition of lasting contributions, remembrance of colleagues who shaped the community, and questions about what SIGSOFT should make possible next.

Overview

What the Celebration Covered

SIGSOFT50 was organized around a simple arc: understand the role SIGSOFT has played, honor the people who built the field, remember colleagues whose work shaped the community, and gather ideas for the future.

Foundations: What SIGSOFT Makes Possible

The celebration begins by naming SIGSOFT's role: a volunteer-led professional society that supports the research, publication, conference, policy, and community infrastructure software engineering depends on.
