Margo Seltzer

Co-Creator of Berkeley DB & Systems Storage Pioneer

Biographical Overview

Co-created Berkeley DB (BDB), the seminal embedded key-value database engine that established transactional ACID durability for software systems worldwide. Seltzer pioneered log-structured file systems, co-founded Sleepycat Software, and received the USENIX Flame Award for lifetime achievement in computer systems architecture.

"The secret to building durable computer systems is understanding where hardware fails and writing software that fails gracefully."

Historical Context & Impact

In short

Margo Seltzer built Berkeley DB in 1992 as a tiny, embeddable database library that ran directly inside an application's address space without a separate server process. It was so fast, crash-resilient, and efficient that it became the invisible backbone of early Internet infrastructure, powering everything from Unix sendmail to Python, Subversion, and OpenLDAP.

Key Technical Breakthroughs & Inventions

Berkeley DB Architecture (1992) Co-created the embedded key-value storage library that became the foundation for high-performance software caching, LDAP, and early Internet servers.

Log-Structured File Systems Authored seminal research into write-optimized file systems and transactional storage layers that inspired modern SSD storage engines.

Sleepycat Software Co-Founder Co-founded Sleepycat Software, proving that open-source software dual-licensing could build a profitable, sustainable infrastructure company.

USENIX Association Leadership Served as President of the USENIX Association and Canada 150 Research Chair in Computer Systems at the University of British Columbia.
