In Memoriam
Researchers in this directory who are no longer with us
The Top 100 and the regional pages list living researchers only, so the directory stays accurate for anyone using it to make contact. This page remembers the 1 researchers from the ranked pool who have passed away, plus a separate listing of foundational figures whose careers predate the digital publication record our pipeline reads from. Each name links to a full profile.

Foundational figures
The pipeline behind this site ranks researchers whose work appears on arXiv or in OpenAlex, which mostly means careers active from the mid-1990s onward. The names below predate that coverage. Their work is the bedrock on which modern research is built. They are listed in birth order. Click any name for a full profile.
