# List of systems scientists
A systems scientist studies organized wholes — how [[Feedback|feedback]], [[Hierarchy|hierarchy]], [[Information|information]], and [[Emergence|emergence]] make a cell, a firm, or an economy behave as one thing — and this directory maps the people who built that project, grouped by generation and school. The groupings are working conveniences, not walls: [[Cybernetics|cybernetics]], [[Systems_theory|general systems theory]], [[Operations_research|operations research]], [[Systems_engineering|systems engineering]], and [[Complex_system|complexity science]] share problems, tools, and in many cases the same people. Names below link to vault articles; the institutional map lives at [[List_of_systems_sciences_organizations]], and the vocabulary at [[Glossary_of_systems_theory]].
## Precursors and founders of general systems
