Victor R. Lesser
Victor R. Lesser researches multi-agent and blackboard systems. He earned a Stanford computer science doctorate in 1973 and worked on Carnegie Mellon’s Hearsay-II speech-understanding project. He used the architecture to study knowledge, search and control. He joined UMass Amherst in 1977 and became emeritus in 2011. His later work covered distributed sensors, task allocation and real-time AI. He also helped establish the international multi-agent research community through conference and organizational leadership.

Timeline
-
1966–1973
Mathematics and computer science
Lesser received a Cornell mathematics degree in 1966 and a Stanford computer science doctorate in 1973. He later held postdoctoral and research roles at Carnegie Mellon on Hearsay-II speech understanding.
-
From late 1972
Architect a speech-understanding system
Hearsay-II began in late 1972, with Lesser as system architect under Raj Reddy. Its blackboard architecture brought together different knowledge sources through an opportunistic search process.
-
1977–2014
Organize distributed AI research
He served on the UMass faculty during 1977–2011 and directed its Multi-Agent Systems Laboratory until it closed in 2014. His research included sensor networks, distributed task allocation and scheduling, extending coordination questions beyond speech understanding.
-
1995–1998
Build a multi-agent research community
Lesser chaired the first International Conference on Multi-Agent Systems in 1995 and became founding president of IFAAMAS in 1998. These roles helped organize a field concerned with interaction and coordination among autonomous computational agents.
